High Power Industrial Mains Surge Suppressor Explored

Last Updated on January 3, 2024 by Swagatam Leave a Comment

highenergyvaristor

In this post I have explained a high energy surge suppressor circuit using high capacity industrial MOVs for suppressing high current mains surges in industrial electrical lines. The Circuit Problem: I’ve been reading a lot of your design ideas and I am extremely impressed with your designs. I don’t have anywhere near your level of […]

Using an NTC Thermistor as a Surge Suppressor

Last Updated on January 2, 2024 by Swagatam 166 Comments

ntc 2

A Negative Temperature Coefficient (NTC) thermistor is a device which is able to suppress switch ON current surge due to its initial higher resistance at room temperature. However, as the NTC suppresses the initial surge current, it warms up causing its resistance to drop to nominal levels and this in turns allows the current to […]
