A ceiling fan moves Counter clockwise & a pedestal fan clockwise.....y the difference????
I have a shop heater with a 1/3 hp capacitor start, induction motor driving the fan. Intermittently, the fan motor speeds up significantly for several seconds (15-60 sec) then slows to normal operating speed. The manufacturer suggested changing the capacitor which made no sense, but I did it to no avail. Could this possibly be caused by the centrifugal switch intermittently reconnecting the start winding?
How can you calculate in detail the VA burden of current transformer used for Restricted earth fault protection? Please understand that the CT required here is Class PX or X. Also please show the calculations for knee point vtg, stabilizing resistor, magnetising current.
