2 Ph = 440V since the voltage measurement in 3-Ph is done between two phase only.

11 kg trivevter meter has rating of -/5amps. And pt ratio11000/110v and is connected with 11kv ct/pt unit of cr ratio 75/5amps. And pt ratio of 11000/110v while checking accuracy of meter with HT Accuchek meter what value of PT ratio and CT ratio to be filled in Accuchek meter
