[ammeter]MS-500P Distribution Network Capacitive Current Measuring Instrument

2026-6-16 15:50:48

MS-500P type distribution network capacitor current tester. This new intelligent tester directly measures the capacitance current of the distribution network from the secondary side of the PT. Compared with traditional testing methods, this instrument does not need to deal with the primary side, so there is no risk of testing. There is no need to take complicated safety measures or wait for lengthy scheduling commands. Simply connect the measurement line to the open triangular end of the PT to measure the capacitance current data. Due to the injection of weak out of frequency test signals from the PT opening triangle, it will not have any impact on the relay protection and PT itself, and avoids 50Hz power frequency interference signals. At the same time, the output terminal of the tester can withstand 100V AC voltage. If a single-phase ground fault occurs during measurement, it will not damage the PT and tester. Therefore, no special safety measures are needed, making this work safe, simple, fast, and the test results accurate, stable, and reliable. The tester adopts a large screen LCD display and a Chinese menu, which is very easy to operate. It is small in size, light in weight, and easy to carry for outdoor operations. The wiring is simple, the testing speed is fast, and the data accuracy is high, greatly reducing the labor intensity of the tester and improving the work efficiency (suitable for capacitor current testing of 6-35kV distribution systems).

purpose

FZY-3 mining stray current measuring instrument is used to test the stray current of steel rails, cable sheaths, metal grids, etc. in underground coal mines. Prevent stray current from exceeding the specified value and causing electric sparks. Ensure the safety of the mine.

DC mode: (+) 0~100mA~500mA~2.5A~10A~50A
Its original error: DC gear+2.5%
Communication file+5%

Precautions for FZY-3 Mining Stray Current Tester

Before measurement, insert the test line into the internal test line hole respectively, and insert both ends of the connecting wire into the two sockets respectively, adjust the pointer of the meter head to make it indicate the zero line.
Place the test rods connected to the terminal posts at the two points being tested (such as steel rails, cable sheaths, coal, etc.) and set the switch to the appropriate position. The indicated value on the meter head is the stray current value between the two points being tested. When the pointer turns right, it is positive, and when it turns left, it is negative.
When measuring stray voltage, the connection in the two-color column can be forked, and the meter head indicates the voltage value, with mA corresponding to mV and A corresponding to V.
When the unknown stray current is large, it should be set to the maximum range first, and then gradually reduced until it reaches the appropriate measurement range. The instrument should be placed horizontally.
When the measured current is greater than 5A, the instrument should only perform short-term measurements. When the measured current is greater than 10A, only instantaneous measurements can be performed.
The instrument should be placed in the (off) position when not in use.
