Product Application
Lightning damage is one of the main factors affecting the safe operation of power grids and factories and mines. The proportion of distribution line tripping caused by lightning strikes in total distribution network faults exceeds 60%.Once damaged by lightning strikes, it will directly affect the safe and reliable operation of the power grid and cause unforeseen serious consequences.At the same time, due to the large number and wide distribution of lightning arresters (MOAs), it brings huge daily operation and maintenance, power outage maintenance, and fault handling manpower and economic pressure. Therefore, our company has developed an online monitoring system for lightning arresters, which is applied to the online monitoring of lightning arresters in various occasions.
