The importance of testing and monitoring surge protective devises for IT systems

Lightning, which is categorised into distant, nearby or direct lightning strikes, may cause transient over voltages. Even if the point of strike is several kilometres away, the energy entering the buildings via the conductors might still destroy electrical and electronic consumers. Lightning current arresters provide protection by safely conducting this high electric energy to the ground via the equipotential bonding system of the building. Transient over voltages are not only caused by ...
