According to the national standard GB311-64 and the "Precautionary Test Rules for Electrical Equipment" issued by the former Ministry of Hydropower, it was designed to meet the requirements of the power system for high-voltage voltage Transformer and multi-frequency induction pressure-resistant test equipment. It is widely used in AC voltage test of 35-220KV voltage Transformer in power system to assess the main and longitudinal insulation strength of Transformer. It can also be used for induction pressure test of winding of motor and Transformer, and can also be used for short-term operation. 150HZ power supply.

The triple-frequency power supply generator uses the saturation characteristics of the magnetic circuit to take out the third harmonic voltage with the largest component in the harmonic, and acts as a power source for the generator to perform frequency multiplier and pressure multiplier tests on the induction coil type electrical products.; To check the coil insulation strength, pressure level.

It consists of a three-phase five-column Transformer(or three single-phase Transformers), a single-phase regulator, a reactor, and a control part. According to the requirements of the user, the shape can be holistic or can be divided.
