MEGGER IS USED 2 MEASURE D INSULATION RESISTANCE OF ANY
CABLE SO THAT ANY LEAKAGE BETWEEN THE INSULATION CAN BE
KNOWN AND MEASURES IN MEGA OHM...........

AND EARTH TESTER IS USED TO MEASURE THE LOW EARTH
RESISTANCE OF BETWEEN ANY TWO POINTS WHICH IS ALWAYS LESS
AND IN OHMS.............................

i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.
