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", utilizes the saturation characteristics of the magnetic circuit to extract the third harmonic voltage with the largest component among harmonics as the power supply for the generator, and conducts frequency multiplication and voltage multiplication tests on inter-turn, inter-section, and inter-layer of inductive coil electrical products; to assess the insulation strength and withstand voltage level of the coil.
◆ Principle of Triple Frequency Induction Withstand Voltage Test Device is used to detect the interlayer, inter-turn, inter-section, and inter-phase insulation of transformer and mutual inductor windings through longitudinal insulation induction tests, which is an important item to verify whether the winding meets the requirements.
◆ For power transformers, voltage transformers, and other test objects, in addition to conducting external power frequency high voltage tests on the main insulation of fully insulated transformers, it is also necessary to conduct induced high voltage tests on the longitudinal insulation of transformers and the main insulation of semi-insulated transformers.
