3 5045How do we calculate tranmission line losses of a 132 KV tranmsission line. Please give some quick tips?
2 5784in a silicon diode we can measure .7v in a voltmeter.but why we can't use this voltage for using?
1440We have 2 no. 4MW DG set. and GEB supply. But, we running, only 1 DG set. when we done APFC/Power factor setting : 0.90, then winding temp. Low. but when setting done : 0.83, then Winding temp. increase. WHY Why ? ? ?, plz give me answer.
4 5382how can calculate static 3phase 4wire CT & PT operated energy meter constant when calibrating using refference meter suppose we have 11kv/110v PT and 30/5A CT, the meter constant is 160imp/kwh, where meter is showing MW energy? give me solution which constant i feed in my refference meter for calibration of energy meter?
