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 4996an 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 ??

hi I have done 3 yrs diploma in electrical engg after 10+2. I have 16 years of work experience into design proposals sales and engg application development in LV/MV swithcgear and sub station automation field. I want to apply for immigration to new zealand but I am not sure whether I qualify or not since I dont have a degree. Can anyone advice? Thanks Riz

When we have earthing mesh or underground earthing network in industrial plants, weather we have NT-S or NT-C-S kind of earthing system, so eventually weather we must use 4 or 5 wire in 400 volt level (For example 3×150+70 mm2 or 5×150 mm2) in this connection I would like to know exactly the paragraph of IEC or IEEE number
