KG-500A Capacitance Current Tester

Introducerea Produsului
KG-500A automatic capacitance current tester, directly from the secondary side of the PT to measure the capacitance current of the distribution network, compared with the traditional test method, the instrument does not need to deal with the primary side, so there is no risk of testing, no need to do complicated safety measures and wait for lengthy scheduling commands. The capacitance current can be measured simply by connecting the measuring wire to the open triangle end of the PT.
Since the injection from the PT opening triangle is a weak cross-frequency test signal, it will not have any impact on the relay protection and PT itself, and avoid the 50Hz power frequency interference signal, and the output end of the tester can withstand 100V AC voltage, if there is a single-phase ground fault in the measurement system, it will not damage PT and the tester. Prin urmare, there is no need to do special security measures, so that the work becomes safe, simple and fast, and the test results are accurate, stable and reliable. The tester adopts large screen LCD display, Chinese menu, the operation is very simple, and small size, greutate redusă, easy to carry outdoor operations, simple wiring, fast test speed, high data accuracy, greatly reducing the labor intensity of the tester, improve the work efficiency.

Caracteristicile produsului
1, siguranţă: no need to deal with the primary side, just connect the measurement line to the open triangle end of the PT can measure the capacitive current data, the test process is simple.
2, digital anti-interference technology: the instrument filters out the influence of power frequency interference voltage on measurement through Fourier algorithm, and calculates the amplitude and phase of the output signal, so as to obtain the measurement results. This method greatly reduces the influence of 50Hz power frequency interference signal on measurement.
3, the protection function is complete: the instrument has a high-power resistor to limit the output signal current to ensure that the instrument does not damage the PT in the case of extreme damage. The high-power output components of the instrument use high-voltage devices to ensure that when the distribution system is abnormal and the opening triangle voltage is too high (up to 100V), the devices can withstand the impact of the voltage before isolation.
