main feature
The instrument for the voltage level of the zinc oxide surge arrester on-site monitoring
(Live test) and the laboratory (power outages) test.
Can measure zinc oxide arrester full current (RMS), resistive current (maximum), frequency reference voltage and active power and so on.
In line with the People's Republic of China electric power industry standard "DL474.5-92 on-site insulation test implementation guidelines - arrester test" requirement.
