DISTRIBUTION AUTOMATION Abstract— This White Paper on‚ “Power systems” addresses the working process‚ benefits and challenges of implementing Distribution Automation in electrical power distribution sector. The demand for electrical energy is increasing every day. Today over 24% of total electrical energy generated in India is lost in transmission (6%) and distribution (18%). The electrical power deficit in country is currently about 18%. Therefore reduction in distribution

short circuit is a fault in which current bypasses the normal load. An open-circuit fault occurs if a circuit is interrupted by some failure. In three-phase systems‚ a fault may involve one or more phases and ground‚ or may occur only between phases. In a "ground fault" or "earth fault"‚ charge flows into the earth. The prospective short circuit current of a fault can be calculated for power systems. In power systems‚ protective devices detect fault conditions and operate circuit breakers and other
