The power frequency withstand voltage test device consists of a power frequency test transformer and a withstand voltage control box, which perform insulation strength tests on electrical appliances, electrical components, etc. under specified voltages.
The insulation oil dielectric loss tester is a high-precision instrument used for measuring the dielectric loss angle and volume resistivity of liquid insulation media such as insulation oil.
The ultra-low frequency high-voltage generator should have an automatic grounding discharge device, and the residual charge on the test sample should be automatically discharged within 5 seconds under the rated capacitance and rated output voltage.
