Motor power factor correction
I’ve been playing around in Excel again. If any one wants a copy of this sheet send me a PM. I’ll also send the updated FLC sheet as well.
A quick note about the PF sheet, for multiple motors you’ll have to decide when during the start up of a group of drives the group PF kicks in. it’s not good practice for it to come in on initial start up.
 
Just as an aside, years ago I’d installed 2 new MCC panels. Got a phone call from the site engineer “there’s a couple of parcels for you in the loading bay”. Intrigued I went to collect them, 2 oil filled 50 & 60 KVAR capacitors that looked like Noah had forgotten to put them on the ark. So they got cobbled in to the system.
Later I asked him how he calculated the rating, “I didn’t, I found them in the back of the stores”. I’ve just used the spreadsheet, he was 2% out!
 
Can somebody give sizes of capacitors needed for PFC and starting of 3phase induction motors of various sizes(kw/rpm/design code).At least give a link.
