If the fault current is 2000 amps, the relay setting 50% and the C.T. ratio is 400/5, then the plug setting multiplier will be
CT ratio is 400/5 CT rated current is 5A relay setting is 50%, relay will operate for=5*50/100=2.5A fault current is 2000A so plug setting multipier = fault current/realy setting*CT ratoio =2000/2.5*400/5 =10A
CT ratio is 400/5 CT rated current is 5A relay setting is 50%, relay will operate for=5*50/100=2.5A fault current is 2000A so plug setting multipier = fault current/realy setting*CT ratoio =2000/2.5*400/5 =10A
CT ratio is 400/5
ReplyDeleteCT rated current is 5A
relay setting is 50%, relay will operate for=5*50/100=2.5A
fault current is 2000A
so plug setting multipier = fault current/realy setting*CT ratoio
=2000/2.5*400/5
=10A
Thank you sir
DeleteOhhh thanks I gonna mad for this
DeleteI HOPE GUYS....YPOU WILL GET IT CLEARLY
ReplyDeleteKEEP GOING ON PRAC
Give me a Solution.....how to find
ReplyDeleteCT ratio is 400/5
DeleteCT rated current is 5A
relay setting is 50%, relay will operate for=5*50/100=2.5A
fault current is 2000A
so plug setting multipier = fault current/realy setting*CT ratoio
=2000/2.5*400/5
=10A
