Different technical losses that takes place in Transmission and Distribution system:
1) Losses due to random growth of sub transmission &distribution system. planned growth/expansion maintains the losses to optimum values as the system conductors and other components are judiciously selected. 2) Losses due to large scale rural electrification through long 11KV & LT lines unbalanced loading 3) Losses due to many stages of transformation. (Large no. of transformers). 4) Un balance loading on three phases 5) Losses due to unsatisfactory reactive power compensation. 6) Losses due to poor quality of equipment used.
