Mains spike protection
Web11 dec. 2014 · To make the mains voltage collapse there is a lot of current flowing into your heater for a short time. An inductor will choke this, while allowing the 60 Hz current to flow. An example value of 1 mH will present a 0.4 ohm reactance to the mains frequency current, so will drop a few volts with a 2 kW load. WebSurge protection devices involve the use of surge suppressors or protectors and surge arresters. Suppressors protect equipment from voltage spikes. They block or short to …
