FAQ

1.How long does an SPD last?

How long a MOV-based SPD can last depends on the frequency and duration of the surge it experiences. Each time the MOV is switched on to divert the surge to the ground, its life decreases slightly. The larger the surge, the greater the degradation of MOV. A single hit at 20kA may reduce the MOV's lifetime to 15 hits at 0.2kA. So depending on the size and duration of the surge SPD encounters, it may last a day to suppress a large surge, or it may last for years to suppress a smaller surge.

2. How do surge protection devices work?

A surge protector or surge suppressor is an appliance or device designed to protect electrical equipment from voltage spikes. Surge protectors attempt to limit the voltage provided to electrical equipment by blocking or short-circuiting any unwanted voltage above the safety threshold.

3.What is distributed (cascaded) surge protection?

Distributed protection, cascading protection, or coordination is the process of coordinating protection between the main service entry and the internal branch switchboards of a large facility. Typically, surge guards (SPDS) with high surge handling capabilities are installed at the service inlet, while SPDS with lower surge ratings will be installed on branch panels or dedicated power supplies that power sensitive equipment. This approach can further include point-of-use SPDS along long lines that terminate in sensitive or critical equipment.
