Electrical Losses Calculation Using Substation Energy Balance Process on La Electricidad de Caracas

This paper shows the experience of La Electricidad de Caracas, Venezuela, developing and commissioning the on line substation energy balance system. Using automatic process of tele-metered energy from all substations of the network, as an useful tool for the evaluation of the electrical losses and an optimal way to detect high incidences areas and early detection of abnormal reader or operation of the energy meter according to their historical consumption. A statistical algorithm with similar day energy consumption methodology is used for detecting abnormal energy values as a trigger to estimate a better one
