XHJS1000R Dielectric Loss Tester adopts digital notch technology to avoid the interference of power frequency electric field on the test, and solves the problem of accurate measurement under strong electric field interference. It can be powered by a generator, and equipped with an oil cup and temperature control device, it is capable of testing the dielectric loss of insulating oil.

• Built-in power supply, booster and standard capacitor;
• Positive/reverse wiring, internal/external standard capacitors, internal/external test voltage and self-excitation method;
• Fully automatic measurement of inductance, capacitance and resistance with angle display;
• Equipped with multiple protection measures against input voltage fluctuation, high-voltage current, output short circuit, power failure, overvoltage, overcurrent, temperature anomaly and other faults.
