Brief introduction:
Current action and leakage monitor for MOA (MONITOR), series-wound between arrester and earth, is a device to monitor arrester’s real-time condition, monitoring and displaying leakage current and its action times under the normal operation. Through monitoring the ill problem as damped, some potential accidents will be pre-failed. Therefore, the operating reliability is improved.
That the shell is of stainless steel of strong erosion-proof and good screen effect, which keep outer magnetic field away and lessen the effect of distribution of capacitance and current, makes the accurate measurement of operating current.
Service Condition:
1.Used in indoor or outdoor;
2.Ambient temperature is from -40°C to +50°C;
3.Sea level altitude is not higher than 2000m;
4.System frequency is 50Hz or 60Hz;
5.Not used in place under strong shock or impact, or where the metal parts are liable to corrode seriously.
