specs for a 4000 watt 60hz snubber?
When the power goes off, I have an in-line inverter system (Trace 2500) to provide AC to my house. The power lines in my area being above ground, lightning sometimes hits the poles and gives huge spikes and surges. Doesn?t happen often, but when it does the next morning people complain about there TV?s and computer?s blowing up and so on. I decided to put a home-brew 4000 watt spike protector before the inverter to protect whatever is on it. I was thinking some heavy-duty 150V varistors accros neutral-hot-ground, and a snubber. About the snubber; looking at some resources, I?m still confused. In my case, AC power should it be:
- L in series with the hot line, C after that across hot and neutral?
- To slow down the spikes at 60Hz, what should the values be?
- Will this handle 4000 watts?
- Any suggestions on winding my own L (core, turns, wire size)?
Help is appreciated!
