how can we minimize the off load losses of a distribution transformer which is required to be energized 24x7 ?? capacity of the T/F is 1250 KVA and off load losses are around 2.0 KW.. can we use capacitor bank at the secondary of such a T/F to overcome off load losses? please elaborate briefly...thanks
2 4993an off load but energized 11/0.4 KV, 1250 KVA T/F has a power factor of 0.65(capacitive)..!! why is it so, though T/F being an inductive device ??

An ISP is granted a block of addresses starting with 150.80.0.0/16. The ISP wants to distribute these blocks to 2600 customers as follows. a) 200 medium size businesses; each needs 16 addresses b) 400 small businesses; each needs 8 addresses c) 2000 households; each needs 4 addresses Design the subblocks and give the slash notation for each subblock. Find out how many addresses are still available after these allocations.
