how we identify between current transformer and potential transformer without having it name plate?
5 12822How can we select suitable capacity generator for three phase load (inductive load) and how to take study analysis in 3 three phase load system ?
2149A group of machines (wind turbines) connected with 33KV feeder and each machines are having individual VCB. The 33KV feeder connected with 110KV/33KV substation. The 33KV feeder tripped by over current at Substation and fault recorded at Substation as OC-R&Y phase. Same time the group of machines VCB tripped by over voltage, the fault recorded voltage was above 66KV by numerical Under/Over voltage relay. While grid drop time, this much of voltage hike is possible?
1 3418I have running 4 generator in paralel.All generators Voltages is same(470 V),KW also same (100 KW) but only No2 generator Amper is high than another generators. DG No:1,3,4 470V,100KW, 150 A DG No:2 470V,100KW,400 A

sent to a site and asked to explain how you would like a twenty seven flour building should be supplied with lighting and sockets plus a water boiler.
If we connect a motor and generator together (I mean that the generator gives the motor electricity and the motor gives the generator movement) regardless the losses. Will the generator still generate and the motor still move?

Which are resistive loads & which one are inductive loads : Refrigerator, Split air conditioner, ceiling fans, well pump, fluoresecent bulbs, T.V, CRT Monitors, Adsl Routers, C.P.U, Printers, Deep Freezers, Speakers, DVD Players, Microwave oven etc. ? Output Power for these Appliances Would be same like this : P = V * A * P.F Or would be changed ? thanks
Consider three heater bank connected in 3 phase star with neutral.Each heater bank connected in each phase.So each phase get 230 volts supply.my question is,during balance condition, current flow in neutral or Not
