How to calculate approximate load loss of a distribution transformer by knowing %ge imp of transformer?
in a silicon diode we can measure .7v in a voltmeter.but why we can't use this voltage for using?
Why an ac systems are preferred over dc systems?
Dear all, I want to use Induction motor to open and close a 1 ton door. How much power do I need. Thanks
if we apply 1000ADC instead of 100ADC or We apply 50ADC instead of 100ADC,What will be happened in the test result value.Pl explain
generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
is it true there's a big difference in using Cummins or Denyo...especially power output or leakage
at what basis/standard we have to arrive the current density of aluminium/ copper in busbar?
Name the types of motors used in vacuum cleaners, phonographic appliances, vending machines,refrigerators, rolling mills, lathes, power factor improvement and cranes.
What will happen if we on 200kvr capacitor bank(11kv in bus)If there is low load on transformer (1.5 mva 33/11 kv)
what is the advantage of connecting capacitors in delta than in star?
List the time domain specifications.
what will happens if one phase is missing for 33/11kv power transfomer and why?
Is the theorem applicable to ac sources?
What is the effect of positive feedback on the stability of the systems?
