2019-12-11

ETCR9330B Large Caliber Wireless H/L VoltageHookType Current Meter connect with the insulation rod, can be used for current measurement of the lines with insulation skin below 60kV or bare wires high voltage lines below 35kV. Online measurement and with data hold, data storage and wireless transmission and other functions, Its special hook type current meter can be easily approached to the measured wire by insulation rod, which can be directly hung on the line for measurement, saving time and more effective. Widely used in substation, power plant, industrial and mining enterprises, detection stations, electrical maintenance departments for current detection and field electrical work etc.

It can also replace the H/L voltage turns ratio tester, which can measure the H/L voltage current of the primary circuit and secondary circuit respectively, and then calculate to get the H/L voltage turns ratio. Insulation rod is portable, with moisture-proof, high temperature resistance, impact resistance, bending resistance, high insulation, telescopic and other characteristics.
