1.0 OBJECTIVE

To provide instructions for electrical testing of Protection Equipments before putting

into service. It included visual inspection of the Protection Cubicle’s for proper

installation and cleanness, to verify the correct operation and to verify equipments meet

the acceptable requirements.

2.0 ACCEPTANCE CRITERIA

This procedure applies to the following testing for Protection System.

1) Visual Check of Protection Equipments

2) Protection Cubicle Mechanical and Electrical Functional Tests

3.0 PROCEDURE

3.1 VISUAL CHECK

The system is checked with mentioned items below visually.

3.1.1 Missing Equipment

The devices and equipments that are shown on the drawings are checked to be

mounted

3.1.2 Cable Connections

Power and control cable connections are checked according to drawings

3.1.3 Earthing of Panel

Panel should be earthed from the earthing busbar or earthing terminal

3.2 CUBICLE ELECTRICAL AND MECHANICAL FUNCTIONAL TEST

The systems is functionally tested with mentioned items below as electrical and mechanical.


6/12




3.2.1 Mechanical Checks of Cubicle

The panels are checked that its door and moving parts are operating well

3.2.2 Polarity of DC Voltage

Before energising the system, firstly the terminal connections are checked. After

supplying DC voltage to relevant system, it should be sure that the polarity is

correct by measuring on L(+) and L(-) terminals.

3.2.3 Internal Functional Test

Internal circuitry of panel is checked to be working, regarding the drawings.

3.2.4 External Functional Test

Signals between panels, CB Commands and other equipments of the system isverified according to drawings.

3.2.5 Relay Software Download and Interlocking Conditions

Prepared relay settings file is downloaded to device. Inputs and Outputs are

checked by connection to relay. Interlocks over the relay (CFC etc.) are checked,

regarding the drawings.

3.2.6 Secondary Voltage-Current Injection

All measurements of current and voltage circuits are observed with secondaryinjection.

3.2.7 Simulation of Protection Functions

Protection relays are tested for trip limits by simulation of fault conditions. Trip

signals are also observed. (Omicron156/256 or eqv. is used.)


7/12




4.0 TEST AND COMMISSIONING SCHEDULE

According to updated time schedule, which is submitted separately.

5.0 PREREQUISITIES

1) Protection Panel should be installed.

2) External cable connections should be completed.

3) AC and DC power should be prepared.

4) Panel Grounding should be completed.

6.0 PRECAUTIONS AND NOTES

The following shall be done in order to made safe prior to starting of Protection

Equipment testing

1) Equipments which is related with Protection system should be mounted and

tested before starting Protection Equipment tests.

2) Warning types shall be installed around the HV Switchyard’s in order to provideunauthorized access to testing area.

7.0 TEST EQUIPMENT

Testing equipments with necessary test certificates will be informed later.

8.0 RESTORATION

In case of necessity for processing on the commissioning tests, some revision could be done on

secondary drawing by informing responsible designer.
