Product Introduction:
XSN-CT901 high and low voltage CT ratio variable tester can measure the high voltage primary current and low voltage secondary current of the high voltage metering device of 35KV and below system without disconnecting wires and continuous electricity on site, and calculate the variable ratio and ratio error. The high-voltage clamp meter (hereinafter referred to as the clamp meter) is installed at the end of the high-voltage insulation rod to collect current signals. When working, wireless transmission is adopted to send the collection results to the handheld terminal, which directly collects the secondary current of the low-voltage current transformer. Handheld terminals will be according to the received data, real-time computing, current transformer primary/secondary current, variable than electricity parameters, such as at a glance, clamp table adopts the design of clamp type connection insulation rod jog, gently pull can clamp enter and exit a conductor, smoked pull type high voltage insulation lever elongation can be up to 5 meters, ensure the safety of the operation process.
