Product description

Product Introduction

　　The insulation oil dielectric loss tester meets the requirements of GB/T5654-2007 "Measurement of relative permittivity, dielectric loss factor and DC resistivity of liquid insulating materials", and is used to measure the dielectric loss (tgδ) and capacitance (Cx) of various insulating liquids. The NR7410 insulation oil dielectric loss tester can identify whether there is moisture and impurities in the insulation oil, judge its aging degree, and the quality of insulation performance. It is widely used in the measurement of dielectric loss and capacitance of transformer oil, capacitor oil and cable oil. Light weight and beautiful appearance.

Main Features

　　◆ Electromagnetic induction heating technology

　　The instrument adopts high-frequency electromagnetic induction heating technology, which ensures uniform heating, fast heating speed, short time, accurate temperature control, and is not affected by the ambient temperature. Single-chip microcomputer control and calculation, realizing automation, high precision of capacitance and dielectric loss measurement, stable data, and good repeatability;

　　◆ Wide voltage range

　　The output voltage is continuously adjustable from 300V to 2000V, suitable for the voltage level requirements of different samples. Users can select and control according to the sample;

　　◆ Ground protection

　　If the grounding wire is not connected or the grounding is poor, the instrument will automatically display a Chinese prompt. There is a short-circuit protection circuit, oil cup short-circuit or high-voltage output short-circuit protection;

　　◆ Automatic calibration of empty cup

　　At 2KV power frequency, the measured dielectric loss of the empty cup is less than 0.005%, and the capacitance value is 60PF±2 PF, ensuring the accuracy of the measurement.
