wind power installation
Motor soft Starter. How does it work?
Hi. My house runs on a generator. I have a problem with the ACs when they kick in. each AC (and there are three of them, one on each phase) pulls 18 Amps as when the compressor kicks in. Is there a way to make it have a ’soft start’? Here’s an excerpt from an article I read on the web:
“One method is to use the same wire used to feed power to the input of small HP AC drives and create an air core reactor by winding the feed wire into a coil, with a diameter of the width of a hand, about 75 turns and tie wrap the coils. This is done in each input phase. In many installations, these �handmade coils� will provide sufficient inductance to slow the current and limit over voltage shutdowns”
So can I put this 75 turns winding at the input of each AC so that i can reduce the start up current to its operating current of 8 Amps?
Your advise would be very much appreciated
it may work. there are commercially made soft start units that you can install that may work better. you can also wire the units so that they can only start one at a time and never together.
