Answer Posted / sumesh s l
even though the system is balanced third harmonics gets
added up.(r-phase sin3wt,y phase/b phase :sin3*(+/-120wt)
same as sin3wt.that is all harmonics component of 3 and
multiple of 3 added up...so neutral current may not be zero..

Operation of isolators.
My question is whether bellow formula is correct to find bus size for 46kA for 0.5 second & what is RT in bellow formula. formula to calculate the size of busbar to withstand the thermal stresses due to currents with duration of 0.2 sec to 5 sec. Sp = RT( I x I x t) / K Where Sp – is the cross sectional area of bus bar in millimeters. I - is the value of AC fault current. t - is the operating time of disconnecting device in seconds. K – is the factor depending on the material of the conductor, insulation and initial and final temperature. Value of ‘k’ for copper is 143.

how to find 5 kilo meter long under ground 33 kv cable fault location if IR VALUE shows 0.05 M ohm @5000 volt.and cable fault locator shows some time fault distance 3 kilo meter ,3.7 kilo meter and some time 1 kilo meter? now how to find the fault location that where is leakage. note--it is tested with 5000 kv megger and insulation resistance is 0.05 M ohm. and some time 0.03 M ohm comes.
