Capacitive Bridge Tester

Overview

With the development of China's power industry, capacitor compensation devices have experienced unprecedented growth. However, this has been accompanied by a significant rise in capacitor accident rates, including severe mass casualty incidents. To prevent parallel capacitor accidents and ensure the safe and reliable operation of the power grid, State Grid Corporation has formulated "Measures for Preventing High-Voltage Parallel Capacitor Accidents." Among them, it explicitly states that...Regularly measure the capacitance of individual capacitors in capacitor banks, and it is recommended to use a measurement method that does not require disconnecting the wiring to prevent oil leakage from the casing due to the stress caused by disassembly.

    This instrument is designed to address the issues encountered during the measurement of high-voltage series capacitor banks at substation sites, and it takes reference from...GB3983.2-1989"High-Voltage Series Capacitors"DL/T840-2003The "Technical Conditions for the Use of High-Voltage Series Capacitors" and other national standards were specifically developed, mainly for measuring high-voltage series capacitor banks of reactive compensation devices.

    This instrument employs the latest high-speed mixed signal microprocessor, featuring high integration. It synchronously collects the voltage and current signals of the test items, automatically calculating the capacitance value and reactive power equivalent. Field measurements of capacitors can be conducted without removing the connection lines, simplifying the testing process, effectively enhancing work efficiency, and avoiding damage to electrical equipment. After the test, it automatically calculates the capacitance value per phase, total capacitance value, and other parameters, highly improving operational efficiency..Easily detect changes in capacitor quality and conductor faults between devices. Additionally, this instrument features data storage andUSBCommunication function eliminates the need for on-site data copying, ensuring the integrity of measurement data.
