Inspection and tests1) Type tests, which have been carried out by an independent testing laboratory on the similar products, shall be submitted with the tender as follows:Shorttime current test;Temperaturerise test;Lightning impulse test on primary winding;Wet test for outdoor type transformer;Determination of accuracy.
2) Routine tests, which shall be made by the manufacturer on each supplied individual product at the manufacturer's factory, shall be submitted to the Purchaser upon the goods to be delivered. These tests shall be carried out as follows:Verification of terminal markings;Powerfrequency withstand test on primary and secondary windings;Partial discharge measurement;Powerfrequency withstand test between sections;Interturn overvoltage test;Determination of accuracy.-
3) Acceptance tests (sample test), which have been carried out by an independent testing laboratory on supplied typical voltage transformer, including:Powerfrequency withstand tests on primary and secondary windings;Determination of accuracy1)We offer the similar type test report LCZ-35
( because 35KV is stardared voltage in our country ,this voltage adapt below 35kv current transformer )
