I have a question, I visit 01 site and face a problem, there is 2.5 ton Air Con working, when air con compressor is running at that time rectifier voltages are increasing upto 290-295 v and rectifier is giving main high alarm (rectifier is APC single phase), before starting compressor rectifier voltages was 230v. when air con is going off rectifier voltages are decreasing smoothly at its actual voltages 230v. Load on Genset phases is this: Red-13.5 amp AC (Air Con load), Yellow-1.7 amp AC (BTS lights etc.) and Blew-4 amp AC (telecom system load), Genset phase to phase and neutral to phase voltages are also ok. These are 10 sites having same system and same rectifier APC brand at every site 02 genset are working but the problem is same at all these 10 sites. What will be the reason behind???

When testing an earthing connection, we use a 60 or 100 candle bulb with a phase connected direct from supply and the other wire to the new earthing provided.If the bulb glows then the earth is ok.Else earth connection is not Ok. So, why dont we can use all the home appliances taking a single wire from the phase and the return connection to Earth instead of return connection to neutral?
