Electrical Power System Losses.pdf

1、The term Electrical Power System Losses is not easy to define. Meanwhile wecategorize losses into two different types. Technical and non technical. Event if this work ismainly based on technical losses, it is necessary t

2、o understand the meaning of both. Energy losses occur in the process of supplying electricity to consumers due to technical andnon technical or commercial losses. The technical losses are due to energy dissipated in thec

3、onductors and equipment used for transmission, transformation, sub- transmission anddistribution of power. These technical losses are inherent in a system and can be reduced toan optimum level. The losses can be further

4、sub grouped depending upon the stage of powertransformation & transmission system as Transmission Losses(500kV/220kV/110kV/66kV), as Sub transmission losses, and Distribution losses (below500KV/220KV, 110KV/66KV). The co

5、mmercial losses are caused by pilferage, defectivemeters, and errors in meter reading and in estimating unmetered supply of energy. This workis based on the analysis of losses, methods of losses minimization or reduction
