Introduction to Automatic Capacitor Tester
The current measurement unit of the power capacitor tester can also be used for measuring electrical equipment such as CVTs and arresters, providing multi-functionality in one device.
The automatic capacitor tester mainly solves the problems encountered when measuring capacitance values of capacitors at substation sites, such as the need to disconnect connecting wires for on-site measurement, which not only involves heavy workload but also easily damages capacitors; and the low fault detection rate caused by the output voltage of the voltmeter.
Characteristics of Distribution Network Capacitance Bridge Tester
◆ No need to disconnect busbars, one-key fully automatic measurement, high precision, good stability, leading domestic technology.
◆ Automatic range conversion, large-screen LCD display, Chinese menu operation prompts, data storage and printing capabilities.
Technical Specifications of Automatic Capacitor Tester
> Adopting a bridge circuit structure, the standard capacitor and the tested capacitor serve as the two arms of the bridge circuit. When measuring the capacitance value of the capacitor, the test voltage is simultaneously applied to the standard capacitor and the tested capacitor. The processor collects the current signals flowing through both via sensors and processes them to obtain the capacitance value of the tested capacitor.
> Due to the synchronous sampling technology of the standard capacitor and the tested capacitor, it is immune to fluctuations in the power supply voltage; in addition, the measurement process is fully automatic, avoiding errors caused by manual operation.
