Our plant havehas a 3 phase line to line connection when iI test the voltage from line to line in the supply side of the main breaker it reads 230 volts but when iI test line to ground,line line 1 reads 196 volts,line line 2 is 111 volts and line 3 is also 111 volts also. IsAre these readings ok? And whenWhen the main breaker is turned on, the reading from line 1 to ground is 0,line line 2 to ground is 230 volts and line 3 to ground is 230 volts.

Line to ground voltage

Our plant have a 3 phase line to line connection when i test the voltage from line to line in the supply side of the main breaker it reads 230 volts but when i test line to ground,line 1 reads 196 volts,line 2 is 111 volts and line 3 is 111 volts also. Is these readings ok? And when the main breaker is turned on, reading from line 1 to ground is 0,line 2 to ground is 230 volts and line 3 to ground is 230 volts.
