More losses in present case can be attributed to life poor maintenance and environmental aspects.
Feeder losses in power system.
Total losses due transformers in the feeder circuit is 8 57 of the total input to the substation.
The formula for calculating the feeder loss according to the feeder type and length is as follows.
Total annual iron loss 25 kva tc 100 x 3 x 8760 1000 2628 kwh.
Figure below shows the typical connections of the antenna feeder system in an indoor base station.
Lower power and energy losses are reduced by raising the load factor which evens out feeder demand variation throughout the feeder.
I will explain it with reference to a substation.
T d losses energy input to feeder kwh billed energy to consumer kwh energy input kwh x100.
Loss load factor 0 8 x lf2 0 2 x lf load factor actual load maximum load 9.
Transmission losses are approximately 17 while distribution losses are approximately 50.
The distribution system in developing countries suffers from the problem of low voltage and high energy loss.
Total annual iron loss.
This quantity of loss is seemingly little high as compared to normal losses of 5 to 6 in a feeder circuit.
The technical losses are due to energy dissipated in the conductors and equipment used for transmission transformation subtransmission and distribution of power.
Transmission losses is approximate 17 while distribution losses is approximate 50.
Total annual iron loss 63 kva tc 200 x 3 x 8760 1000 5256 kkwh.
Distribution sector considered as the weakest link in the entire power sector.
The problem of the losses and voltage drop in distribution feeders dependent on each other and varies with the pattern of loading on the feeders.
Energy losses occur in the process of supplying electricity to consumers due to technical and commercial losses.
There are two types of transmission and distribution losses.
Total annual iron loss 100 kva tc 290 x 3 x 8760 1000 2540 kwh.
Distribution sector considered as the weakest link in the entire power sector.
Consider a distribution substation which receives power from a transmission line.
Total annual iron loss in kwh iron losses in watts x nos of tc on the feeder x 8760 1000.
The feeder loss per 100 meters is related to the frequency band.
Total transmission and distribution losses are about 40 50.
Commercial loss total energy sent total energy billed technical loss the above methodology is applied in the two feeders to estimate the theoretical loss in the feeder.
Feeder loss db feeder loss per 100 m db 100 m feeder length m 100.
