Split-type Triple Frequency Power Generator
Darui Electric recommends
Special transformer for induced overvoltage withstand test of transformers and instrument transformers
The triple frequency transformer produced by Huatian Electric is designed according to the Chinese standard "GB311-61" and the "Regulations for Preventive Tests of Electrical Equipment" issued by the former Ministry of Water Resources and Electric Power in January 1985, to meet the requirements of the power system for high-voltage instrument transformer frequency-doubling induced overvoltage withstand test equipment. It is widely used for AC withstand voltage tests of series-excited voltage transformers at 35-220kV levels in power systems, to assess the main and secondary insulation strength of instrument transformers. It can also be used for induced tests on windings of motors and small transformers; it can also be used as a 150Hz power source for short-term operation.
