how we can set the IDMT relay.
for 11KV OH system what will be typical per KM "R" "L" "C" parameter. for 33KV OH system what will be typical per KM "R" "L" "C" parameter. for 33KV UG system what will be typical per KM "R" "L" "C" parameter.
anyone please send transformer parameter design formulas & details of tap changer ? plz i have interview this week its more helpful for me ?
I have a relay contact rated at 220v dc which is supplied with a 24vdc from the panel,for it to trip the dampers(24vdc).What if the application of the relay changes so that it should work at its rated 220vdc then will it work at 24vdc supply given or any other consideration needs to be taken .....
how to determine Sq.mm size of finolex power cables.
1- What is the Polarization Index number be good for 15KV 3c#500MCM electrical cable? 2- Can I use the IEEE Std 43-2000 to perfom the PI test? Thanks
We have two parts in generator, electrical & mechanical. how it works?
we have provided 30 nos. relay contacts in panel.I want to know how do we do the numbering for the relay contacts as per any applicable standards
How does HT work & Voltage required?
sir, Is their any measuring unit of knoking? please explian?
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...
