Product Overview

XHJS1000R Dielectric Loss Tester adopts digital notch technology to eliminate the impact of power frequency electric field on testing, overcoming the difficulty of accurate measurement under the condition of strong electric field interference. It can be powered by generators, and the configuration of oil cup and temperature control device enables the testing of insulating oil dielectric loss.

Performance Features

• Built-in power supply, voltage booster and standard capacitor for integrated use;
• Configure positive/reverse wiring, internal/external standard capacitors, internal/external test voltage and self-excitation method to meet diverse testing demands;
• Achieve automatic measurement of inductance, capacitance and resistance, with angle value display;
• Be equipped with comprehensive protection measures against input voltage fluctuation, high-voltage current, output short circuit, power supply failure, overvoltage, overcurrent, temperature deviation and other abnormal situations.
