It tests the alternating leakage current or sustained current under the operating tension of various classes of voltage zinc oxide lightning arrester, and the frequency reference voltage under the frequency reference current.

Main features:
It can be used in live-line tests and laboratory power cut off tests.
It can display voltage/current waveform and harmonic number.
The inner memory makes it very convenient to check the historical data at any time.
The main technical indexes:
Test items: full current(0-20mA), resistive current(0-20mA), active power(0-8W), operating tension(kV).
Current test range:0-20mA
Voltage test range:0-400V
