What is the effect of impedance on the heat losses in case of AC system??? Does heat losses really depends on the impedance or depends only on resistive component only..??
4 6074In a poly phase circuit if clamp on meter shows same load on three phases and their sum on neutral then why we use three and a half core cable or maximum the same size of core as that of phase?

power transmission pole used one support , that only for support or earthing
advantage and disadvantage of team work?
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

i am going to give the JSEB,RANCHI exam for power plant,so i need some samples of papers related to that,so please send me these papers by my mail id.
Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
