What is the diameter of electromagnetic field around a 11000/415v transformer ? Dose it affect people who live 3-4 meter beside it?
1646when we start the tube light, then it takes initially 1100 volt, after glow it takes 120 volt?(when we give 220 volt a.c.)

1772One of our gas turbine generator unit "1st stage rotor ground fault" alarm was occured several times. we tried to measure some voltage vulue ground fault protection relay (UNS3020a made by ABB and we measured the value of: Ground: 0.9VDC 5V: 5.8VDC 24V: 23VDC u+: 300 – 350mVAC Rf1: 17.5mVAC Rf2: 17.6mVAC The unit still running and the alarm was reset. As of 6pm yesterday and unitl now no alarm happened again. I our protection relay was defective?
1 3677when meggering a 3ph,480v oil reservoir heater on a regen gas compressor, why do I get a reading to ground when meggering phase to ground? shouldn't it read opened or is there something that makes it read closed? on the same heater, when ohming, it reads open. thanx
