Huazheng HZRG-III Transformer Capacitance And Inductance tester

This instrument is specifically designed to address the challenges in the field measurement of high-voltage shunt capacitor banks in substations. It was developed based on national standards such as GB3983.2-1989 (High Voltage Shunt Capacitors), DL/T840-2003 (Technical Conditions for the Use of High-Voltage Parallel Capacitors), and JB5346-1998 (Series Reactors). The instrument is primarily used for measuring the reactive power compensation devices, including high-voltage shunt capacitor banks and reactors.

Equipped with a high-speed microprocessor, this instrument synchronously collects both the voltage and current signals from the test product. It then automatically calculates the equivalent capacitor and inductance values. There is no need to disconnect any wiring, simplifying the testing process and significantly improving work efficiency. After testing, the instrument automatically calculates the capacitance of each phase and other key parameters, making it easy to identify capacitor quality changes and detect faults in the connecting conductors between devices.

    I. Functional Characteristics

    1.This instrument is capable of measuring a single capacitor within a parallel capacitor bank without the need to disconnect any wiring. It can also measure the inductance of various reactors, making it suitable for a wide range of field applications.
    2.During measurement, the instrument displays the measured capacitance or inductance values, and it can also show additional data such as voltage, current, frequency, impedance, phase angle, and more.
    3.The instrument uses an output from a variable frequency power supply, which significantly enhances its anti-interference capabilities. It can be used in high-strength magnetic fields without affecting measurement accuracy.
    4.The instrument features a 7.0-inch, 1024×600 HD screen with touch operation. The display is clear and visible both day and night, and it supports easy switching between Chinese and English, making it user-friendly.
    5.It is equipped with a large-capacity, non-volatile memory that can store up to 500 sets of measurement data.
    A USB interface is available for storing any set of measurement data (limited by the capacity of the USB drive).
    6.The instrument includes a built-in, high-precision real-time clock for accurate date and time calibration.
    It has a built-in printer for printing measurement data directly.
    7.The instrument can be controlled via an Android phone or tablet. By following the WeChat official account and downloading the dedicated app, users can manage the entire testing process, store test data, and upload it conveniently.
