Product Details

Single-phase microcomputer relay protection tester manufacturer Working Principle

Due to the use of standard capacitor and tested capacitor synchronous sampling technology, it is not affected by power supply voltage fluctuations; in addition, the measurement process is fully automatic, avoiding errors caused by manual operation, thus it has the characteristics of good stability, good repeatability, accuracy and reliability.

Single-phase microcomputer relay protection tester manufacturer Features

1. It has the characteristics of small measurement workload, fast and simple operation, stable performance, accurate measurement, and high fault detection rate.

2. It adopts a bridge circuit structure, with the standard capacitor and the tested capacitor 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.

3. Due to the use of standard capacitor and tested capacitor synchronous sampling technology, it is not affected by power supply voltage fluctuations; in addition, the measurement process is fully automatic, avoiding errors caused by manual operation, thus it has the characteristics of good stability, good repeatability, accuracy and reliability.
