The working principle and product application of a fully automatic capacitance and inductance tester

Fully automatic capacitance and inductance tester, abbreviated as capacitance and inductance tester. The fully automatic capacitance and inductance tester adopts a bridge circuit structure, with standard capacitors and the tested electrical container as the two arms of the bridge circuit. When measuring the capacitance value of the capacitor, close the test switch K, and apply the test voltage to both the standard capacitor and the tested capacitor. The processor collects the current signal flowing through both capacitors through sensors and processes it to obtain the capacitance value and resistive component of the tested capacitor.

Due to the use of standard capacitors and the synchronous sampling technology of the tested electrical container, the tester is not affected by power supply voltage fluctuations; In addition, the measurement process is fully automatic, avoiding errors caused by manual operation, thus having the characteristics of good stability, good repeatability, accuracy and reliability.

Product application:

The fully automatic capacitance and inductance tester is specially developed under the guidance of the expert working group of reactive power compensation devices to address the problems that exist when measuring the capacitance value of a single capacitor in a parallel capacitor bank in a substation. It focuses on solving the following problems:

1. The on-site measurement of a single capacitor requires the removal of connecting wires, which not only requires a large workload but also easily damages the capacitor;

2. The low output voltage of the capacitance meter leads to a low fault detection rate.

3. The instrument for measuring the inductance of reactors has the characteristics of small measurement workload, fast 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 lightning arresters, with the function of one machine with multiple functions.

The ZC-800C fully automatic capacitance and inductance tester has the characteristics of small measurement workload, fast and simple, 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 lightning arresters, with the function of one machine with multiple functions.
