there is flow current.**** THANKS

Answer / nur.asidik

we can calculate no load loss of TR, but you need to know impedance of TR

Answer / k.prakashchandra

Short the LV side ,increase voltage on HV ,till you get the rared current. The percentage of this voltage against rated voltage is % impedance . if you connect a watt meter you get copper losses . With open circuit apply rated voltage ,to measure the iron losses with a watt meter .

could i arrange a faulty and healthey battery bank togather in parallel , if your ans is not then why?
