1 FOREWORD

Ausgrid is responsible for the management and operation of Ausgrid’s electricity supply network. This network, which supplies the most populated area in Australia, is a major infrastructure investment. The network is required to operate economically and reliably under all weather and other environmental conditions.

As part of its formal asset management approach Ausgrid’s aim is to provide a series of cost-effective modular designs for use in developing the distribution network. For these designs to meet the requirements of Ausgrid, they are required to satisfy a range of functions far wider than basic electrical performance and economy. These functional requirements include meeting all statutory and safety obligations; operating effectively under adverse environmental conditions and utilising approved new components that have demonstrated reliability.

This Network Standard lays down the requirements for site selection and construction of 3-phase or single phase pole mounted substations that meet the requirements of Ausgrid.

This standard may be amended or updated at any time to reflect improvement in design, technology advances etc. The Accredited Service Provider shall ensure that the latest version of this standard is used for the equipping of the substation to which it applies.

The requirement of this standard must be adhered to.

Any deviation from this standard must be submitted to Network Engineering for approval prior to implementation.

Network Standard NS109 Design Standards for Overhead Development and NS112 Design Standards for Commercial/Industrial Developments must be complied with for projects that involve an extension to either HV or LV mains. The selection of substation type ie kiosk or pole mounted, shall normally be dependent on the mains installed. In general, kiosk substations shall be installed in locations with underground HV mains and pole mounted substations shall be installed in locations with overhead HV mains.

The installation type will be specified by the Customer Service Planning and Negotiations Officer.

8.1 Pole Mounted Substation Site Selection The pole mounted substation shall be located in an area that is well-drained and clear of overhead obstructions. The substation and access route shall not be within an area that is classified as hazardous by Section 9 of AS3000.

The immediate area surrounding the pole mounted substation should provide a firm, level base with sufficient space to safely erect a standard 4m/7m extension ladder. A space for the ladder 1 metre square with the centre of the space 1.5 metres from the base of the pole is satisfactory.

The visual impact on the streetscape must be considered when locating the pole mounted substation.

A review of environmental factors shall be carried out and the risks assessed at the stage prior to selecting the site.

A pole mounted substation shall not be located:

within an overhead or underground transmission line easement.

where possible, within 3 metres of a concrete driveway

in locations which are clearly hazardous as detailed in Ausgrid’s documentation NS167 Positioning Poles and Lighting Columns

in reclaimed land, land-fill sites, wetlands or similar locations

at sites with an unsatisfactory evaluation of environmental impact

within the easement or footpath allocation of another utility (eg communication carrier, gas, water, rail, etc) without the prior written permission being obtained from the relevant utility – refer to NS130 Appendix ‘C’ for footpath allocations.

To minimise oil spill risk to the environment, pole mounted substations should not be located in close proximity to rivers, creeks, natural or man made water courses, stormwater drains, or paved surfaces or concrete aprons that drain to the stormwater system.

Wherever possible, pole mounted substations should not be located:

Within 40 metres upstream of a waterway or sensitive environment, such as a wetland, national park or nature reserve,

Within 5 metres upstream of a grated drain or pit, where there would be less than 500mm of permeable strip between the substation pole and the kerb,

Within an area of high ground water, where the ground water would be normally less than 1 metre below ground level,

Within an area prone to flooding, or a drainage path, or a stormwater ponding area,

Adjacent to steep downhill slopes, of 10% grade or greater,

Within high bushfire risk areas.

Additional factors affecting pole positioning are detailed in NS167.

9 SUBSTATION RATINGS

Ausgrid’s standard pole mounted substation design type, alternatives and options will be detailed in the Design Information document. The transformer rating can be from 16kVA single phase up to a maximum of 400kVA 3-phase.

The Ausgrid electricity network has been designed to the following maximum fault levels:

At 11kV the maximum fault level is up to 18.4kA

At 415 volts the maximum fault level at a pole mounted transformer is up to 13.3kA

The actual future maximum fault levels for the substation shall be included in the Design Information document.

There are three types of 11kV dropout fuses currently approved.

Fault Level Fuse Base & Carrier Type

11 CONSTRUCTION STANDARDS APPLICABLE TO ALL POLE MOUNTED SUBSTATIONS

The following construction standards apply to all pole- mounted substations installed in Ausgrid supply area:

The pole mounted substation shall be sited in accordance with the Locality Sketch.

The pole shall be installed in accordance with NS128 Specification for Pole Installation.

The orientation of the transformer on the pole shall be aligned for correct phasing and where possible the pole climbing access is on the side opposite the direction of traffic flow.

The pole shall be set in concrete from the edge of the hole to the pole and from the pole butt to 350mm below final ground level. The concrete shall be wet mixed and tamped every 200mm during installation.

Note: Poles must not be concreted up to ground level.

A curing period of 7 days is required before installing the transformer on the pole where the soil conditions is deemed as poor. In good soil conditions, installation and construction on the same day is acceptable.

Note: Before installing the transformer on the pole either on the same day or in the subsequent days, the stability of the pole must be assessed by an experienced worker to ensure the safety of personnel. The provision of the overhead mains and/or stay poles will increase the pole stability.

Bolts, nuts and washers used for the connection of all electrical equipment and earthing conductors to pole mounted substation equipment shall be stainless steel grade 316 or better. Before installation of any stainless steel bolt/setscrew, the thread shall be lubricated with specially formulated anti-seize grease incorporating nickel, (eg Loctite Nickel anti-seize stockcode 177212 or equivalent).

Where the lubricating grease will be in contact with an electrical insulating medium, the supplier of the insulating medium shall be consulted to ensure product compatibility.

Stainless steel bolts must never form part of a current carrying circuit, they must be only used to clamp the current carrying components together.

All steelwork, including bolts passing through timber, shall be hot dipped galvanised to AS-1650 (Hot dipped galvanising on ferrous articles) and/or as appropriate AS-1214 (Hot dipped galvanised coatings on threaded fasteners )

The threaded section of all galvanised bolts shall be coated before installation with KOPR-KOTE anti-seize lubricant, stockcode H19942.

Stainless steel conical (volute) washers shall be used on all bolts used to secure crossarms to a pole or equipment to a crossarm or pole. The approved method for a crossarm attached to a pole is to use a bolt fitted with a square washer, through the pole, gain block and crossarm then use 1 x square washer, 1 x SS conical washer, 1 x round washer (galv) and finally the nut.

Equipment mounted on a crossarm similarly requires either 2 x square washers, or the steelwork square washer, plus 1 x SS conical washer, 1 x round washer and a nut. Both cases require a large surface area in contact with the timber to prevent indentation. The conical washer is used to allow for shrinkage of the timber.

LV surge diverters shall be installed on each phase of all pole transformers in accordance with the relevant LV detail drawing.

21 March 2008

NS122

Where the transformer is of the free air breathing type, a check shall be made to ensure the breather is free to breath. Any seal fitted to prevent oil spillage during transport shall be removed.

Hexagonal compression lugs compatible to the cable size and crimp die and tool compatible with the lug shall be used for all terminations on bare and insulated cables greater than 6mm2.

Note: Split bolt clamps are acceptable for auxiliary connections as detailed on earthing drawings on the Earth cables.

Bi-metallic hexagonal compression lugs compatible to the cable size and crimp die shall be used for all aluminium to copper terminations.

Shrouds shall be installed on all HV and LV phase bushings and HV surge diverter terminations. Where bare cable lugs extend external to the shrouds, install medium walled mastic lined black heatshrink over the bare lug barrel and cable insulation.

Where 2402mm flexible cable is installed between the transformer bushings and the LV fuses, the interface between the end of the cable and the compression lug is to be covered with a mastic lined medium walled black heatshrink a distance of 50mm either side of the end of the lug to prevent water ingress and oxidation of the flexible conductors.

All poles used for Pole Mounted Substations shall comply with NS128. Appendix E Table 2 ‘Poles for Special Purposes’ which details the specification for the poles used on substations rated 100kVA and above. The pole shall be class A, as specified in Australian Standard AS 2209. The pole shall have durability class 1 hardwood timber, be straight over their entire length, free of perceivable surface cracking and be capped with a galvanised steel pole cap. The poles are to be treated with CCA (copper-chrome-arsenate pressure impregnated). Refer to Table 3 in this standard for details of the pole size and pole strength.

Pole substations may be constructed on existing 12.5 m, 8kN or 12kN poles providing the pole is assessed as being in good condition and having a long life expectancy. (Pole strength requirement for HV and LV mains to be determined by calculations).

Note: A pole shall be deemed to be in good condition following an inspection by a qualified pole inspector to the Network Standard. The pole inspection report shall be forwarded to the Customer Service Planning and Negotiations Officer. A pole cap must be fitted and the pole must have a waist reduction of less than 10 per cent of pole diameter.

Existing single phase substations may be uprated to a 3-phase substation rated less than 100kVA by installing an additional HV drop-out fuse and additional LV fuses and transformer mounting bracket. Transformer LV cables must be to the ‘LV Cable Size’, see Table 2.

HV and LV fusing is to comply with Ausgrid fusing schedule.

In situations where a new pole substation is to be installed into an existing LV open wire construction, the LV open wire construction is to be removed and replaced with LV ABC back to the first pole either side of the new substation.

The transformer mounting bracket used is designed for poles having a diameter between 300 and 360mm at a distance of 8450mm from the butt of the pole. It is important to select a pole having these parameters as scarfing of the pole is not accepted.

The requirements in handling, drilling and after treatment for pole damage are detailed in Network Standard NS128.

A Maximum Demand Indicator (MDI) and associated current transformer which displays the maximum twenty minute demand shall be installed on all 3-phase substations rated at 100kVA and above and on single phase substations where specified.

March 2008 22

NS122

Note: MDI’s are not required on 3 phase substations supplying a single customer unless specified An engraved label, affixed to the MDI shall display the constant K of the MDI.

Pole steps shall be installed in accordance with the pole dressing detail drawing. A minimum distance of 3.6 metres shall be allowed between the finished ground level and the lowest pole step. Pole step spacing shall not exceed 450mm. The clearance from HV equipment to any pole step (especially the earthing bolts on drop-out fuses) shall not be less than 200mm for 11kV and 300mm for 22kV. The pole step must be removed if this clearance can not be achieved.

16 TESTING

Throughout the procurement, construction and inspection phases of the project, the Accredited Service Provider shall carry out checks, measurements and tests as necessary to demonstrate compliance with the requirements of this Network Standard.

The following tests are the minimum required. Their results shall be recorded in the formal Test Report and made available to the Compliance Officer prior to the inspection of the substation.

All specified tests shall be carried out on completion of the installation and before the commissioning of the substation. Ausgrid reserves the right to witness and/or repeat any on site test procedure that is specified in this document.

The Accredited Service Provider shall give the Compliance Officer two working days notice that the tests are to be carried out.

All test equipment and instrumentation used for testing shall have been calibrated by a NATA Registered Certification and Testing Organisation and have a current test sticker affixed. The Accredited Service Provider is responsible for ensuring that test equipment and instrumentation used is traceable.

Results for the test equipment are to be included in the formal Test Report and shall include:

testing organisation name and NATA registration number

test date

instrument number and calibration date

test equipment number and calibration date.

16.1 Transformer Testing The Accredited Service Provider shall conduct the following tests on the transformer and associated equipment:

high and low voltage winding continuity test

Insulation Resistance tests on the total installation

an induced HV test (if required)

Transformer Oil Tests (if required).

Where Ausgrid has not supplied the transformer it must comply with Ausgrid’s current specification. A copy of the transformer specification and routine test results are to be forwarded to Ausgrid’s Negotiating Officer, who will forward the result to Procurement for approval. Upon approval, Procurement is to issue an Ausgrid Transformer Asset Number, (eg T19723) via the Negotiating Officer.

The routine test results shall include all tests as required by AS-2374 Power Transformers – Part 1 General Requirements.

16.1.1 HV and LV Winding Continuity Test HV Windings

Using a 1,000 volt insulation tester, test the continuity of the HV windings.

For a 3-phase transformer

A-B, B-C, C-A on ALL tap positions

For a single phase transformer

A1 –A12 on ALL tap positions

March 2008 32

NS122

LV Windings

Using a 1,000 volt insulation tester test the continuity of the LV winding.

For a 3-phase transformer

a-n, b-n, c-n and n-earth

For a single phase transformer

a1/a2 to a3/a4 with the winding bridges installed

a1 to a3 and a2 to a4 with the winding bridges removed.

16.1.2 Insulation Resistance Tests on Total Installation Test and record the Insulation Resistance for the following using a 1,000 volt insulation tester: (Due to the transformer characteristics, the resistance reading shall not be taken until the test current stabilises).

The insulation resistance of the total HV circuit including the HV fuses shall be measured to earth. (The minimum approach distance to any existing energised HV mains must be maintained.) The transformer tapping switch to be in its final position.

The insulation resistance of the combined low voltage circuits down to and including the connections to the supply side of the low voltage fuses, shall be measured to earth. The connection between the transformer neutral bushing and earth is to be disconnected during the test. All LV surge arresters earth connections are to be disconnected during the test.

HV – LV (with the neutral earth disconnected and LV surge diverters disconnected).

For any transformer the insulation resistance measured shall not be less than:

HV – Earth 200+ M (see note)

LV – Earth 100 M

HV – LV 200+ M (see note)

Note: A reading of 100 M+ is acceptable if this is the maximum full scale reading on the insulation testing instrument.

16.1.3 Induced HV Test This test is required on all new and used pole mounted transformers that have not been previously tested in a factory or workshop prior to energisation. The test may be done in a workshop or depot, or on site. For the purpose of interpreting the safety rules, the voltage applied by the testing device is taken to be the voltage that is present on the High Voltage terminals of the transformer. Due to the presence of high voltage, it is essential to ensure adequate equipment and safety requirements for carrying out this test in accordance with Ausgrid’s Electrical Safety Rules.

All test equipment and instrumentation used for testing shall have been calibrated by a NATA Registered Certification and Testing Organisation and have a current test sticker affixed. The Accredited Service Provider is responsible for ensuring that test equipment and instrumentation used is traceable.

New and refurbished transformers that have been previously tested in a factory or workshop tested do not require this test to be repeated.

For this test the low voltage winding is energised from a test set at 240 volt phase to neutral with the HV winding isolated and one HV terminal earthed. Under this test the other two phases will be subjected to an 11kV to earth voltage, ie an over voltage of 3.

The test is repeated with the HV earth connected to the other phase terminals in turn. The sequence of testing is again repeated with the other LV windings each energised in turn.

33 March 2008

NS122

Note: For a 3-phase transformer, typical results should indicate the current measured should be the same when injecting in ‘a’ and ‘c phases’. There should be a small difference in the current measured for ‘b’ phase injection.

A winding problem would also be indicated by an audible discharge sound from within the transformer.

If the LV injection current measured is inconsistent or an audible discharge is heard, then the transformer is to be rejected and replaced by another transformer.

16.1.3.1 Transformer Oil Tests

Note: Transformers supplied by Ausgrid do not require additional transformer oil tests by Accredited Service Providers. See the following for transformers not supplied by Ausgrid.

FREE BREATHING TRANSFORMERS (not supplied by Ausgrid).

Before inspection of the substation the Accredited Service Provider shall:

Provide to the Compliance Officer test results that are not more than 12 months old from the manufacturer or supplier of the transformer detailing the condition of the insulating oil and PCB content or

Have an oil sample taken from the transformer and tested by a NATA approved testing organisation for water content, dielectric strength and PCB content

The minimum values for acceptance are:

Water content <10mg /kg (10 parts/million)

Dielectric strength >45kV breakdown voltage

PCB content <1ppm none detectable (must be warranted at <1ppm)

SEALED TRANSFORMERS (not supplied by Ausgrid).

Sealed transformers do not require oil tests to be undertaken unless the transformer has been opened and/or repaired.

If it has been opened and/or repaired the oil test requirements for a free breathing transformer shall be met.

16.2 Earth Continuity and Insulation Tests Refer to See section 13.1.1 and 13.1.2.

16.3 Voltage Withstand Test Where required by Network Standard NS161, or where specified by Customer Supply Planning and Negotiations Officer, high voltage underground cables, including commissioning joints, for underground connected pole mounted distribution substations.

The following substation equipment shall be subject to a voltage withstand test in accordance with the relevant Australian Standard.

Note: Voltage withstand tests must be carried out by a NATA approved testing organisation.
