	I had come across a motor which is used for ATT ( Automatic turbine trip ) in NTPC power plants, supplied from germany has the name plate of, 230/400 V, 0.18 KW, 50 HZ, 1.15/0.67 A , Star/ Delta, 0.73 pf. But these values are talling in power equations. __________________ ?????????? ????????? ????????,.........??????? ???????????? ???????? ????. ????????????

	Hello k.dhana Are you making a statement? are you asking a Question? Your Topic is not explaining whether you want an answer or a discussion. What is "talling" ?

	I you are asking what it means (I'm not clear on what you want either), then it means that if you connect it to a 230V supply, you will connect the motor according to the Delta pattern and the current will be 1.15A at full load. If you connect it to a 400V supply, you will use the Star pattern and it will draw 0.67A at full load. Either way, the power factor is 0.73 and the output shaft power rating is 0.18kW (180W). __________________ All I every really wanted to be, was... A LUMBERJACK!.
