♦Insulating sleeve
♦Composite insulating silicone rubber
How surge arrester works
Not all surge arresters protect systems from lightning. While lightning current surge arresters (Class 1) are used to protect against direct lightning surge currents, surge arresters (Class 2) protect equipment from induced surges in electrical wiring. Surge arresters and lightning current arresters from FZDLi Power offer reliable protection against these hazards.
♦ A short and simple overview of a lightning arrester for the non-technical.
The purpose of a surge arrestor is to protect insulation/components from high DV/DT that peak at instantaneous values that are in excess of the breakdown of the insulation or component. Lightning is one common cause of voltage surges.
♦ Another common cause is switching in an inductive circuit.
It is possible to capture the occurrence of a voltage surge. Some surge arresters are equipped with’surge counters’that capture the fact that the arrester has discharged current. It is also possible to use other phenomena (sound measurement, light measurement, electric field measurement, etc) to capture the occurrence of a discharge. Meteorologists routinely capture and record lightning discharges using both ground-based and satellite-based instruments.
