MOVs or metal oxide varistors are devices designed for controlling mains switch ON surges in electrical and electronic circuits. Selecting an MOV for a particular electronic circuit might require some consideration and calculation, I have explained the procedures here. What are MOVs Metal oxide varistors or simply varistors are non-linear surge suppressor devices which are […]

How to Test a MOV (Metal Oxide Varistor) Surge Protector Device
In this article I have explained a set up for testing MOVs which are special devices specified for absorbing instantaneous high surge currents that may accidentally occur in our mains electrical lines. The idea was requested by Mr. Kevin Technical Specifications I’m Kevin Montañez, a university Electrical Engineering student here in Cebu, Philippines. As I […]
