◆ Meet the requirements of "DL/T848.4-2004 General Technical Conditions for High Voltage Test Equipment Part 4: Triple Frequency Test Transformer Device", use the saturation characteristics of the magnetic circuit to extract the third harmonic voltage with the largest component in the harmonic, and use it as the power supply for the generator to conduct double frequency and double voltage tests on induction coil type electrical products between turns, segments, and layers; To assess the insulation strength and withstand voltage level of the coil.

The YHSBP series triple frequency induction withstand voltage test device is used for longitudinal insulation induction testing of interlayer, turn to turn, section to phase insulation of transformers and transformer windings. It is an important project to test whether the windings meet the requirements.

The triple frequency induction withstand voltage test device is used 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 induction high voltage tests on the longitudinal insulation of transformers and the main insulation of semi insulated transformers.
