Triple Frequency Test Transformer
Product Overview: The triple frequency voltage generator is designed according to the Chinese standard "GB311-61" and the "Preventive Test Regulations for 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 frequency doubling induction withstand voltage test equipment for high-voltage transformers. It is widely used for AC withstand voltage tests of series-excited voltage transformers, motors, and transformers in the 35-220kV class in power systems, to assess the main and auxiliary insulation strength of transformers. It can also be used for induction tests on windings of motors and small transformers, and can serve as a 150Hz power source for short-term operation.
Functional Features: 1. Used for AC withstand voltage tests of series-excited voltage transformers in the 35-220kV class in power systems. 2. The triple frequency voltage generator is simple to operate and reliable in performance. 3. Adopts a three-core five-column structure, stable and reliable. 4. Zero-position start, overcurrent protection.
