Answer Posted / gomez jerald
An ACB Is constructed for a particular contact rating at medium voltage .Technical explanation the contacts energize and d energize the arcing air medium during the process is quenched in an open chamber.
VCB is constructed especially for higher rating voltage and the technical term .the arcing during energizing and d energizing is quenched in closed chamber at very low pressure.

how to know the diffrential relay setting of 06mva step- down (delta-star)transformer?
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.
