In legging current reactive power is arise but in leading current which power will be arise ? and in this case, is active power more than rated ?
3 4221I Have 100Ah battery with 650VA Inverter, i WANT TO TAKE a Solar panel to charge my battery, so please suggest me,what rating of solar panel(with solar charge controller) can buy for a load of 450w for 4 hours
1 4818A synchronous motor is operating at a leading power factor .if the applied voltage is decreases ,(the excitation remains constant ) ,the motor current a)increases b) decreases c)remains same d) none of these
2 3048DEAR ALL I have motors ( 10 units )each one is 90kw 380V 50 HZ 1000rpm but new local pwer is 220v 60 hz requierd rpm should be 1000 pleas what the beast solution is used frequncy converter or rewinding all motos or chang all motors thanks

6 63961. Can a 12v DC choke operate a 60v/12w PL lamp ? 2. Can a 230v ballast fire / operate a 60v/12w PL lamps.
1738why battery dc voltage become Half when we check with respect to ground for example 120volts + and - terminals and when we check + terminal with Earth thats 60volts why 60volts same result on 24Volts and with ground 12Volts only expert answer that thanks we can not ground the battery.

HOW TO CALCULATE AMPs OF CURRENT TRANSFORMER IN HT Panel
we 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
