Electrical problems at home related to RPC
"Ignoramus18851" wrote in message
... There are some intermittent problems at home related to me starting my RPC. It is beginning to affect my marriagee. 1. A TV once turned off 2. At another time, our kitchen oven, where me and my son placed some cookies to bake, went crazy and went into a cleaning mode and burned the cookies. I suspect that it is so because the main 10 HP motor takes a comparatively long time (1-2 seconds) to spin up, and draws about 120 amps during this time. I am considering adding some capacitance to increase its starting speed, but would like to double check if this is a step in the right direction. I would turn these caps off after the motor comes up to speed. thanks i Additional starting capacitance would probably help. You might also try power factor correction capacitors directly across the motor windings connected to the single phase supply. Don Young |
