Lightning arrester is an important electrical equipment to protect
power equipment from over voltage in power grid.Normally, the
arrester monitor is used to monitor the arrester's movement and
leakage current. Due to poor sealing, the monitor may enter
moisture or moisture during operation, which may cause corrosion
of the internal components, or other causes that the monitor counter
cannot operate normally, and the leakage current indication is
inaccurate.So "< regulation >" regulation, should check lightning
arrester monitor once a year.The reliability of counter operation is
very important to the power system. It is an important parameter to
record the lightning strike times of arrester in normal operation.It can
provide an important basis for the workers of power system to
inspect the arrester
