Transient surges are a change in fundamental frequency that occur thousands of times a day when using a VFD (variable frequency drive). Standard surge protection devices are voltage triggered only and do not account for these transient surges that can lead to
Lightning and surge protection for photovoltaic (PV) systems
November 12, 2014
Due to their exposed installation sites and large collection areas, Photovoltaic (PV) installations are at a high risk of damage due to both direct and indirect lightning strikes. Since the PV system is connected directly to the building electrical system, the subsequent
Lightning and surge protection for intrinsically safe circuits by DEHN (UK) Ltd
