Product Introduction:



  ◆ Meets the requirements of "DL/T848.4-2004 General Technical Conditions for High Voltage Test Devices Part 4: Triple Frequency Test Transformer Device", utilizing the saturation characteristics of the magnetic circuit to extract the third harmonic voltage with the largest component among harmonics as the power source for the generator, performing frequency multiplication and voltage multiplication tests on inter-turn, inter-section, and inter-layer of inductive coil-type electrical products; to assess the insulation strength and withstand voltage level of the coils.



  ◆ Principle of Triple Frequency Induction Withstand Voltage Test Device is used to detect the longitudinal insulation induction test of inter-layer, inter-turn, section, and phase-to-phase insulation of transformer and instrument transformer windings, and is an important project to verify whether the windings meet the requirements.



  ◆  For power transformers, voltage transformers, and other test objects, in addition to performing external power frequency high voltage tests on the main insulation of fully insulated transformers, it is also necessary to perform induction high voltage tests on the longitudinal insulation of transformers and the main insulation of semi-insulated transformers.
