THE RATING OF ANY MACHINE IS DEPEND ON LOSSES DISUPATION OF
THAT MACHINE.SO IN CASE INCASE OF ELECTRICAL MACHINE THE
LOSEES ARE COPPER LOSES @IRON LOSSES BOTH RESULT IN
DISUPATION OF HEAT .HENCE THE CU LOSS DEPEND ON CURRENT
@IRON LOSS DEPEND ON VOLTAGE.SO THAT PRODUCT GIVES RATING
OF MACHINE.

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.

A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?
