since this day ,voltage in my house is showing 100volts but phase voltage is correct.i found out that the culprit is my microtech 850VA invertor (warraty period off).when i power on the invertor ,voltage in the circuits that are not on the invertor become that much low even without any load on it.but when i power off the invertor.voltage rises to normal that is around 200volts.
what is the problem here ? i also found out that the power cord (input) of the invertor is showing line in all the three terminals when it is on.is it normal or what?
