we all know that in transformer, voltage and current are inversely related i.e. Vp/Vs= Is/Ip....so in standard CT..we have a ratio of 200/5...that means our voltage should increase by ratio of 40..althoug that is not the case...because that requires high insulation level.and pratically not feasible......can anybody clarify my ques.......thanx
2 4153what is the Excaste meaning of CT Saturation?? 10 P 20, 15 VA, what is the meaning of 10, & 20. if the CT polarrity changed what will happened?? what is the differece between measuring CT & Protection CT?? what is the Saturation Point of measuring CT & Protection CT??

1 3935I have 2 KW electric water heater.I am gonna use it in controlling water temp.so I needed to increase or decrease the heating capacity.is there any electrical-electronic circuit for varying the resistance & so current?
1 3211we have 400kv/6.6kv transformer ,it has total 9 taps on HV side with normal tap on tap no 5.when we took the ratio test we observed that ratio was decreasing from tap 1 to tap 5 and was found increasing from tap 5 to tap 9.What is the reason?if anyone have related document then please send me on the email id ankushbahale@gmail.com......plz plz
