HZ2671 High Voltage Insulation Tester 200GΩ for Transformer Cable Motor
Product Description
The HZ2671 Digital Insulation Resistance Tester is a high-precision, industrial-grade testing instrument designed for professional power system inspection and maintenance. It supports five optional test voltages of 500V, 1000V, 2000V, 2500V and 5000V, fully covering routine and preventive insulation tests for various electrical equipment.
Equipped with a high short-circuit current above 1.6mA, the tester can quickly charge capacitive loads such as power cables, transformers and generators, ensuring efficient and stable testing. It provides a wide measuring range from 1MΩ to 200GΩ with accurate test results of ±(5% reading + 2 digits), meeting strict industry testing standards.
Built-in PI and DAR automatic calculation functions effectively help engineers evaluate the aging degree and insulation quality of motor and transformer windings. Adopting guard ring and low-pass filter design, the instrument features strong anti-interference ability and maintains stable data even in complex electromagnetic field environments on site.
With a durable aluminum alloy shell and ultra-lightweight body, the device is easy to carry and suitable for outdoor field operations and high-altitude testing. Powered by a 12V rechargeable lithium battery with low power consumption, it supports long-time continuous work without external power supply, making it an ideal testing tool for substations, power plants, industrial enterprises and electrical engineering contractors.
