Capacitance and Inductance Tester Manufacturer
Darui Electric recommends:
The capacitance and inductance tester is specially developed to address the problems existing in measuring the capacitance of individual capacitors in shunt capacitor banks at substation sites.
Overview
It focuses on solving the following problems:
● Measuring individual capacitors on-site requires removing connecting wires, which is not only labor-intensive but also prone to damaging the capacitors.
● The low output voltage of capacitance meters leads to low fault detection rates.
● Measuring the inductance of reactors.
This instrument features small measurement workload, quick and simple operation, stable performance, accurate measurement, and high fault detection rate. In addition, its current measurement unit can also be used for measuring electrical equipment such as CVTs and arresters, offering multi-functionality in one device.
According to the "Technical Measures for Preventing Accidents in Capacitor Installations," for high-voltage shunt capacitor banks, the capacitance of individual capacitors in the bank should be measured regularly, and it is recommended to use a measurement method that does not require disconnecting the connecting wires to avoid套管 leakage faults caused by stress on the bushings during disassembly and assembly.
