What is the accepted limit to increase the choosen transformer capacity over the load and why ?
Hi Friend I am used multimeter to measure the voltage between R Phase(SS1) to R Phase(SS2). In SS1 is connected with UPS loads. But I am getting voltage between these 2 R Phases. Please give some idea friend
how we can find of current direction(supply comming/out going direction) when a transmission line passing through sides.
what is a bus post insulator? explain its application in a substation.
Why insulation level follows this order? transformer < bus bar < circuit breaker & Isolator < transmission line.
Hi I'm doing my MBA(3rd semester).I applied for the post of ET conducted by BHEL the last year.I cleared the written and lost in personal interview.Again I wrote the exam this time and cleared the written n yet to take the personal interview.Shall I disclose in the interview about my studies.What shall i say if they ask about my change from studies to job
mostly the questions were from machines... d.c. machines, transformer, synchronous and induction all theory paper........ few from power system... but the level of paper was easy.....

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...
