Field testing of MOSAIMS@

Surge arrester is an important protection device installed mostly at the power transmission substation. It is used to safely channel through the overvoltage surge due to the lightning or switching effect to the ground and thus protecting the other vital power equipment at the substation. Ageing or d...
