Product Name: Automatic Capacitance Current Tester (Neutral Point Capacitance Method)
Product specifications: XSN-DR-PT01
Product introduction: XSN-DR-PT01 automatic capacitance current tester directly measures the capacitance current of the distribution network from the secondary side of the PT. Compared with the traditional test method, the instrument does not need to deal with the primary side, so there is no test There is no need to do complicated safety measures and wait for lengthy dispatch commands. You only need to connect the measuring line to the open triangle end of the PT to measure the capacitance current data. Since the weak different frequency test signal is injected from the PT opening triangle, it will not have any impact on the relay protection and the PT itself, and avoid the 50Hz power frequency interference signal. At the same time, the output of the tester can withstand Subject to a 100V AC voltage, if a single-phase ground fault occurs in the system during measurement, it will not damage the PT and the tester, so no special safety measures are required to make this work safe, simple and fast, and the test results are accurate ,Stable and reliable. The instrument adopts large-screen LCD display and Chinese menu. It is easy to operate, small in size, light in weight, easy to carry for outdoor operations, simple in wiring, fast in test speed, and high in data accuracy, which greatly reduces the labor intensity of testers and improves Work efficiency.
