Triple Frequency Induction Withstand Voltage Tester
Darui Electric recommends
Product Features: The triple frequency test transformer is designed to meet the requirements of GB1094.3—85, GB1207, and the electrical equipment preventive test procedures — 1995 for triple frequency induction withstand voltage tests and partial discharge tests. Transformer and instrument transformer induction withstand voltage tests are important tests to verify that the product meets national standards. The longitudinal insulation induction test of interlayer, inter-turn, segment, and phase-to-phase insulation of windings is an important item to verify whether the windings meet requirements. To increase the winding test voltage without causing the transformer or instrument transformer core to saturate excessively and lead to excessive excitation current, the test frequency is usually increased to 10
