Engineering AllOther (1379) What is the Chemical Formula of Mineral Oil used in Transformer. It is Challenged for all Chemical Engineers.
6 25848how i decrease the neutral to ground voltage , thats i read 7v on my digital meter.i dont know about my earth pit.
2 4621why we are using the 2 slope in differential relay?but in busbar differential we are using only one slope. what is the reason.
1 3955in the directional overcurrent and earthfault protection,normally we are setting the angle 45 deg lead for phase fault overcurrent and -45 deg lead for earthfault fro forward direction.but both the fault are operating on the same angle region only.why?how the relay will response?
1846hi to all,i done ccna,now im looking job,but it is very diffcult to get job in networking field,.........i dnt know what im doing wrongly,kindly help me and give the proper way...i have so much of interest in this field only

Help need in transformer !? Hello Friends The parameters of 2300/230 v 50hz t/f is R1=0.286 ohm R`2=0.319 ohm Rc=240 ohm X1=0.73 ohm X`2=0.73 ohm Xm=49.2 ohm Secondary Load impedance ZL=0.387+J0.29 solve the exact equivalent circuit with normal voltage across primery.. I know every thing but i cant find CURRENT I1=? and I`2=? Please help me give solution or only Formula please please...
