Feeder Losses In Power System

The feeder loss per 100 meters is related to the frequency band.

Feeder losses in power system.

Energy losses occur in the process of supplying electricity to consumers due to technical and commercial losses. 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. There are two types of transmission and distribution losses. Total transmission and distribution losses are about 40 50.

If the feeder supplied a total energy of 5 000 mwh the load factor for that month is 5 000 mwh 10mw x 720 0 69. T d losses energy input to feeder kwh billed energy to consumer kwh energy input kwh x100. The distribution system in developing countries suffers from the problem of low voltage and high energy loss. Transmission losses is approximate 17 while distribution losses is approximate 50.

Total annual iron loss 25 kva tc 100 x 3 x 8760 1000 2628 kwh. Consider a distribution substation which receives power from a transmission line. Loss load factor 0 8 x lf2 0 2 x lf load factor actual load maximum load 9. Total annual iron loss 100 kva tc 290 x 3 x 8760 1000 2540 kwh.

Total annual iron loss in kwh iron losses in watts x nos of tc on the feeder x 8760 1000. Total annual iron loss 63 kva tc 200 x 3 x 8760 1000 5256 kkwh. There are two types of transmission and distribution losses. More losses in present case can be attributed to life poor maintenance and environmental aspects.

Total losses due transformers in the feeder circuit is 8 57 of the total input to the substation. Distribution sector considered as the weakest link in the entire power sector. Total annual iron loss. Distribution sector considered as the weakest link in the entire power sector.

The formula for calculating the feeder loss according to the feeder type and length is as follows. Figure below shows the typical connections of the antenna feeder system in an indoor base station. Transmission losses are approximately 17 while distribution losses are approximately 50. Lower power and energy losses are reduced by raising the load factor which evens out feeder demand variation throughout the feeder.

Feeder loss db feeder loss per 100 m db 100 m feeder length m 100. I will explain it with reference to a substation. This quantity of loss is seemingly little high as compared to normal losses of 5 to 6 in a feeder circuit.
