In this video, I show you why a varistor (MOV) is so important. This power meter accidentally received 380 V instead of 220 V and the varistor came into action, sacrificing itself to protect the other components. It did exactly what it was designed to do: take the hit, so the circuit could survive. #electronics #electronicrepair #mov #varistor #surgeprotector #circuitprotection #electricalengineering #shorts #diyelectronics #powerrepair #technicianlife #electroniccomponents #learningelectronics
