What is BUCKBOOST TRANSFORMER and Operation of Buckboost
transformer?
Answer Posted / vasuram
its a dc to dc converter..it can act as buck converter i.e
high i/p voltage to low o/p voltage converter if duty ratio
is higher 0.5 ( or lesser than 0.5 am not sure )
and it can act as boost converter i.e low i/p voltage to
high o/p voltage if duty ratio is vice versa.

I have 2500KVA transformer delta/star,13.8KV/380V provided with LV 4000A breaker. Already I have 2300KW motor feeder with a full load 90%. Is it possible to connect another 1600A from that breaker? If so how the calculation is done?
We have drive feeding an output contactor for a 5000 hp motor @ 5kV application. The motor FLA is 629amps x 1.25% service factor = 786.25 amps The cable that we current have in place between the drive and the output contactor is 350kcmil- MV-105 (parallel cables). Per the NEC table 310.60 (C) (69). This show the cable ampacity is at 615 amps per cable for a rating of 1230 amps. We have derated the cable for the cable tray and the multiple cables application and our calculations show that after the correction factor factor we are at 922amps. 1230 amps x .75% correction factor factor = 922.5 amps. The customer is driving us to then use another safety factor of .25% off of the already derated cable. Can you please provide a longhand calculation for your solution on this application?
