flyback diode (sometimes called a snubber diode,
freewheeling diode, suppressor diode, or catch diode[1]) is
a diode used to eliminate flyback, the sudden voltage spike
seen across an inductive load when its supply voltage is
suddenly reduced or removed.

Define active filter?

As we know diode work on both negative and positive but converting ac into DC we have to given a/c from negative of diode or positive side.please give me answer.

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.
