The triple frequency generator device is often referred to as the induced withstand voltage test device in the power industry



It is a special power supply device specifically used for induced withstand voltage tests on transformers, voltage transformers (PT), and other equipment. Since the power frequency (50Hz) power supply cannot directly meet the withstand voltage testing requirements of some high-voltage equipment (which would cause core saturation), the triple frequency generator successfully solves this problem by generating a high-voltage power supply at 150Hz (3 times the fundamental frequency). 1. Core background: Why use triple frequency? When conducting induced withstand voltage tests on transformers or voltage transformers, we need to apply voltage on the low-voltage side and generate high voltage on the high-voltage side through electromagnetic induction to assess the insulation strength between turns, layers, and sections. Power frequency (50Hz): According to the formula
