NRJC-C Insulation Potential Tester is mainly used for the voltage distribution value of the insulator string of the live measuring line tower with AC line of 35~500kV. It can also be used to measure voltage distribution of various 35kV and AC voltage insulators in laboratory. It is an ideal test instrument and live working auxiliary tool to ensure the safe operation of the line.
Overview
Characteristics
● It adopts an electrostatic structure to measure the potential difference between two points of the insulator and the measured voltage becomes an electric field so the impedance is high and the influence on the system to be measured is minimal.
● The measured signal is internally amplified and finally output as a voltage value by the LCD digital display.
● The operation is quick and simple.
● The measured signal is internally amplified and finally output as a voltage value by the LCD digital display.
● The operation is quick and simple.
