Remote diagnosis of electrical distribution networks

Remote diagnosis of electrical distribution networks contributes greatly to their global performance, obviously on technical grounds but also on 3 economic factors: (1) the reduction of technical losses through a detailed knowledge of all energy flows at various nodes of the network; (2) the optimisation of investments and of operational costs through precise information on the network status and its operation conditions; such information permits the organisation of preventive conditional maintenance (only where needed, when needed); this optimises the return on investment by extending the operating life of equipment without compromising the network technical performance; and (3) the improvement of the energy dependability (availability and quality) through close monitoring of the energy delivery conditions and the identification of the possible need for correction and their most efficient locations. This paper discusses the diagnosis method and the four actions involved in the continuous diagnosis process for a network
