I. Overview:
Zyjs-6000 automatic dielectric loss tester is the power plant, substation and other field or laboratory test of various high voltage power equipment dielectric loss tangent value and capacitance of high precision test instrument. The instrument is integrated structure, built-in dielectric loss test bridge, variable frequency voltage regulating power supply, boost transformer and SF6 high stability standard capacitor. The test high voltage source is generated by the inverter inside the instrument, which is used for the test after the transformer boosts the voltage. The frequency can be changed to 45Hz or 55Hz, 55Hz or 65Hz. Digital notch technology is adopted to avoid the interference of power frequency electric field to test, and fundamentally solve the problem of accurate measurement under strong electric field interference. At the same time, it is suitable for generator power supply detection after all power failure. The instrument is equipped with an insulating oil cup to measure the dielectric loss of insulating oil.
