why batteries are rated in ampere hour
Hi If connecting a temp generator 670KVA .415kv with step up Tx .415/11kv. I am given Generator impedances Z1 Z2 Z0 to 100MVA base. Do I need to work out the generator fault current by using these impedances i.e gen rating / impedance. Then use this as my source impedance for the calculations that follow.
what is diff kav & kvarh?
HOW TO SET THE EARTH FAULT SETTINGS IN ACB????????????
generally rectifying of ac tells. ac signel appear at phase and neutral with respect to frequency by -veand +cycles. but we doesn't experience shock with neutral in house hold ac??????.
what is the difference in using the 125% and the 250% factor of safety in calculating circuit breakers capacity for motors,which is more reliable to use the 125% or 250%??
What is an order of a system.
i am using star-delta connections with reverse/forward direction motion of the 75hp induction motor.What should be the ratings of Main,Delta and Star contactors and why?
Hello sir, pls send me hpcl technical test papers .i am. Appearing for the exam.
WHAT IS AIR GAP VALUE IN MM FOR A 11KV BUSHING OF 11KV/440V DISTRIBUTION TRANSFORMER. AND AIR GAP VALUE OF 25 KV BUSHING OF AT TRANSFORMER OF 25 KV TRACTION. WHAT IS THE CALCULATION FOR THE AIR GAP PERMITTED FOR BUSHINGS AT DIFFERENT VOLTAGES.
what are types of ups?
please tell me formula of 3 phase induction motor under condition{1]when we 3 phase motor starts without load in star or delta connection?thanks
