AJ512 Capacitive inductance (current capacitance) tester
1、 Overview:
The capacitance and inductance tester is mainly used to measure the high-voltage parallel capacitor group and reactor of the reactive power compensation device. Its measurement basis complies with the national standard SJ-255-10300 capacitance measuring instrument. Specially developed for the measurement of high-voltage parallel capacitor banks in substations, it mainly solves the following problems:
On site measurement of capacitors does not require dismantling of connecting wires, simplifying the testing process, effectively improving work efficiency, and avoiding damage to power equipment;
Complete parameter measurement makes it easy to distinguish changes in the quality of capacitors and faults in the connecting conductors between devices;
Large capacity data storage, micro printer and USB communication, no need to copy data on site, multiple ways to save measurement data.
2、 Characteristics of measuring instruments:
This instrument adopts advanced measurement principles and four terminal measurement technology, which can accurately measure and test with good repeatability;
△ Large screen high-definition true color LCD display (800X640 dot matrix), with Chinese character menu prompts for operation;
The LCD screen comes with touch screen buttons, making operation intuitive and simple;
The automatic segmented compensation of △ current linearizes the full range current and improves the measurement accuracy of the instrument;
△ Environmental temperature monitoring facilitates the influence of capacitors on capacitance values at different temperatures;
The new generation USB communication function simplifies the connection with PCs, making it convenient for measuring data transmission and management;
Equipped with a micro printer, test results can be printed on-site without copying data.
