These facilities are used for high-voltage circuit breakers which cannot be tested with only a short-circuit generator. The synthetic test is carried out by combining the
EStablished in 1997, Shandong Taikai Instrument Transformer Co., Ltd is a wholly-owned subsidiary of Taikai Group Co., Ltd. With registered capital of 200 million and total assets of 535 million, we are specialized in manufacturing three products series of instrument transformer, surge arrester and complete testing equipment with voltage from 10kV to 1000kV.
From the test I was able to ascertain the actual impedance of the transformer using, Measured Sec. Voltage/transformer sec. voltage X Transformer Sec. Current/ Measured Secondary Current X . Using the same test result, One should be able to determine the Rating(Capacity of the transformer).
As noted in "Power Factor Testing of Dry-Type Power and Distribution Transformers," by E.J. Maritolli and R. Levi, Doble Engineering Co., you should apply the test voltages shown in Table 1 (click here to see Table 1) when performing a power factor test.
High voltage instruments were set-up next to the power transformer to measure voltages on both sides. A 1 mΩ shunt resistance was installed between transformer neutral and earth on 765 kV side to measure the current circulating through the winding.
It is widely used in power electric system, research institutes, and large mining factories to do the tests of AC DC withstand capability and insulating materials' characteristic for any kinds of high-low voltage power equipments, power cables, generator, etc. Testing transformer is divided into tow kinds of voltage single-stage and cascade.
Single-phase and three-phase transformers for the range above 16 kVA and up to 72.5 kV. These units are designed for power centres, substations and networks; also for pad-mounts. They are used in public distribution systems, commercial buildings and industrial complexes.
High Voltage Electricity transmission cable test equipment is an example of an area of specialist calibration expertise. Drallim service and repair all their range of products. We can meet the challenges of obsolescence by offering updated assembly replacement, for example.
employing test voltages above 10 kV and up to 35 kV yielded very discerning results when copper sulfide was present both in research samples and in actual transformers. This test was termed the "high-voltage power factor tip-up test."
