The triple frequency test instrument is designed to meet the requirements of GB1094.3—85, GB1207, and the preventive test procedures for electrical equipment—1995 for triple frequency induced voltage withstand tests and partial discharge tests. The induced voltage withstand test for transformers and instrument transformers is an important test to verify whether the product complies with national standards. The longitudinal insulation induction test of the interlayer, inter-turn, segment, and phase-to-phase insulation of the windings is an important item to assess whether the windings meet the requirements. In order to increase the test voltage of the windings without causing excessive saturation of the transformer or instrument transformer core, which would lead to excessive excitation current, the test frequency needs to be increased, typically to 100H
