Leakage current value especially resistive leakage current value is larger, then work about electric power personnel will check and test to the arrester,
Whether qualified observe it.Current study show that the leakage current values of arrester are the major criterions for judging arrester quality, movement
Number can only make reference.If staff can monitor meter on-line to arrester by an arrester in substation
Action frequency and leakage current size be observed, but the volume of the meter is larger, is not suitable for being mounted on distribution line network
In.
