How is the voltage distributed when GDT and MOV are used in series？
Jun 25 , 2025
Without lightning surge voltage, that is, under normal power frequency voltage, the voltage distribution of MOV (metal oxide varistor) and GDT (ceramic gas discharge tube) is mainly affected by their electrical characteristics. 1. GDT (Ceramic Gas Discharge Tube): GDT has extremely high parallel impedance (about 1TΩ) and extremely small parallel capacitance (below 1pF) unde...

How to Tell If a Surge Protection Device Is Bad
Jul 17 , 2025
Surge protection devices (SPDs) are essential for safeguarding your electronics from voltage spikes caused by lightning strikes, power outages, or electrical faults. However, like any other device, SPDs can wear out or fail over time. If your surge protector stops working effectively, your expensive equipment could be at risk. Here’s how to tell if your surge protection device is bad a...
