1232in the farm,water tank of 8000 litter capacity situated in 12 meter above.Farm owner want to lift 7000 litter of water within 7 minute to water tank of 12 meter above.which motor having HP rating is suitable for pumping??
1 2235we have two generators different capacity on 15 MW and other 6MW at 11 KV , 15 MW gen. bus short level current 40KA,and 6MW short level current 25KA,, length of cable 100MTR between 6 MW from 15MW gen. for bus coupling . kindly tell any one can we use both NGR OR one NGR from any GEN. BOTH NGR has diff. rating. Tariq pakistan
1209We are dealer in Maharashtra State & We have recd. form C from dealer of Maharashtra State against our E-1 form. Now assessing authority is asking for counterfoil of our E-1 form. But, our E-1 form counterfoil is misplaced somewhere & assessing authority is disallowing the C form which is recd. from Maharashtra State.Please let us know the option for allowing C form?

should %impedance be high or low in a power transformer? if so why?
y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
