Electrical Network Monitoring Systems

System Modelling

Electrical power distribution systems in windfarms, CHP plants, utilities and industry must be modelled before construction to verify proper operation, or during operation in order to solve critical problems. Premium Power supplies and supports the ERACS system modelling tool as developed by ERA Technology of UK. This is a very powerful tool for modelling and analsing networks. It can be used to identify and solve potential network problems
