1 Certificate A Certificate contains a record of a series of type tests carried out strictly in accordance with a recognized standard. The equipment tested has fulfilled the requirements of this standard and the relevant ratings assigned by the manufacturer are endorsed by TÜV Rheinland. The Certificate is applicable only to the equipment tested. TÜV Rheinland is responsible for the validity and the contents of the Certificate. The responsibility for conformity of any apparatus having the same designation as the one tested rests with the manufacturer. The Certificate contains the essential drawings and a description of the equipment tested. Detailed rules are given in TÜV Rheinland’s Certification procedure.

2 Type Test Report A Type Test Report contains a record of a series of type tests carried out strictly in accordance with a standard recognized by TÜV Rheinland. The test object has fulfilled the requirements of this standard and the relevant ratings assigned by the manufacturer are endorsed by TÜV Rheinland. The Type Test Report is applicable only to the test object. TÜV Rheinland is responsible for the validity and the contents of the Type Test Report. The responsibility for conformity of any apparatus having the same designation as the one tested rests with the manufacturer. The Type Test Report contains the essential drawings and a description of the equipment tested. TÜV Rheinland issues six basic Type Test Certificates (Reports) may be issued by STL Guides. STL Procedure They are as follows:

2.1 Type Test Report of Complete Type Test This Report provides the verification of all the rated characteristics of the equipment as assigned by the manufacturer, by means of the performance of all type tests specified by the Standards.

2.2 Type Test Report of Dielectric Performance This Report provides the verification of all dielectric ratings by means of the performance of the appropriate type tests specified by the Standards.

This sentence will display on the front page of Performance Test Report if the tests have been performed in accordance with a recognized standard, but the series of tests does not completely fulfil the requirements for a Certificate of Compliance (for example, if the number of test series is not a complete series of type tests).The Report contains verified drawings and a description of the test object. The condition of the test object after the tests is assessed and recorded in the Report.

3.2 The tests have been carried out in accordance with the client’s instructions. Test procedure and test parameters were based on a recognized standard. This sentence will display on the front page of Performance Test Report if the number of test duties, the test procedure and the test parameters are based on a recognized standard and related to the ratings assigned by the manufacturer. Verification of the drawings (if submitted) and assessment of the condition after the tests is only done on the client’s request.

3.3 The tests have been carried out according to the client’s instructions. This sentence will display on the front page of Performance Test Report if the test shots, test procedure and/or test parameters are not in accordance with a recognized standard.

4 Standards When reference is made to a standard, and the date of issue is not stated, this applies to the latest issue, including amendments which have been officially published prior to the date of the tests.

5 Official and uncontrolled test documents The official test documents of TÜV Rheinland Laboratory are issued in bound form. Uncontrolled copies may be provided as loose sheets or as a digital file for convenience of reproduction by the client. The copyright has to be respected at all times.

6 Accuracy of measurement In the table of test results the measured quantities are given in three digits. This method of presentation does not indicate an accuracy. The guaranteed uncertainty in the figures mentioned, taking into account the total measuring system, is less than 5%, unless mentioned otherwise.

7 Qualified by CNAS (China National Accreditation Service for Conformity Assessment) Xi’an High Voltage Apparatus Research Institute Changzhou Co., Ltd.( )have been entered in the CNAS-register for laboratories under resp. CNAS L0223 for the testing services as defined in the Field of Accreditation. The accreditation is carried out in accordance with ISO/IEC17025

a) Test current:1375 A(1.1 Ir required by client), 50 Hz, ambient temperature:28.4℃ b) The CB assembly with in GELPAG-MSS-12/1250-31.5 switchgear (LSC2B) performed the temperature-rise test. c) The test was made indoors in an environment substantially free from air and air velocity did not

merchant exceed 0.5 m/s. d) Temperature-rise measurement point refer to measurement position diagram of the temperature-rise test

provided by the manufacture. e) The ambient air temperature was recorded during the tests by means of at least three thermocouples

devices equally distributed around the switchgear and controlgear at about the average height of its current-carrying parts and at a distance of about 1 m from the switchgear and controlgear. The thermocouples was protected against air currents and undue influence of heat. In order to avoid indication errors because of rapid temperature changes, the thermocouples was put into small bottles containing about 0.5 L of oil. Level 1 tolerance T-type thermocouples were adopted.

f) The type and sizes of the temporary connections. Current supply incoming busbar cross-section:80x10 mm2x 2 m (Length) Current supply outgoing busbar cross-section:800x10 mm2x 2 m (Length)

-Test object for circuit s energized only during switching operations. -When the switching device has an automatic breaking device for interruption of the auxiliary circuit at the end of the operation, the circuit shall be energized 10 times, for either 1 s or until the automatic breaking device operates, the interval between the instant of each energizing being 10 s or, if the construction of the switching device does not permit this, the lowest interval possible. -The maximum temperatures of windings are determined by the resistance method by calculating the temperature rise and adding this value to the ambient temperature. -The temperature rise of copper windings is calculated from the formula:

t = (R2 – R1)(234.5 + t1) / R1 – (t2 – t1) where t is the temperature rise; R1 is the resistance at the beginning of the test; R2 is the resistance at the end of the test; t1 is the ambient temperature at the beginning of the test; t2 is the ambient temperature at the end of the test. -Test results:
