KESBP Triple Frequency Test Transformer
DARUI Electric recommends for you
Product Features: The triple frequency test transformer 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 that the product meets national standards. The longitudinal insulation induction test of winding layers, turns, sections, and phase-to-phase insulation is an important item to verify whether the winding meets requirements. To increase the test voltage of the winding without causing over-saturation of the transformer or instrument transformer core, which would lead to excessive excitation current, the test frequency must be increased, typically to 10
