12 Customer benefits Benefits for utilities and energy consumers, in secondary substation, are: q q q q Improved quality of the power supply, indexes as SAIDI and SAIFI reduced. Less and shorter outages and improved voltage quality Improved operational grid efficiency, reliability and availability Improved tools for the network operators and the field crews Optimal utilization of the distribution network Improved economy minimizing network losses and amount of not supplied energy Fault analysis: density of fault, failure rate, criteria for the classification of the faults Utilize the network more efficiently with more stability Measurement analysis: power flow and quality Ensured safety for personnel Less need to travel to locations with difficult access Less need to work in dangerous environments Improved maintenance, also proactive activities.
