The updated knowledge of low voltage connectivity data (link between MV/LV transformer and phase with end user) results critical for the correct management of electrical distribution networks. With updated connectivity information a GIS solution may calculate transformer load balances, find critical network spots before any incident occurs, prepare maintenance task planning, ..., i.e., improves electric supply quality.
In order to cope with electric utility needs, Ariadna Instruments has designed the IF-3 Low Voltage phase identifier. This equipment determines the connectivity data between subscribers and phase of an MV/LV transformer substation in a fast, easy and reliable way. Ariadna IF3 works without de-energizing the line, so electrical supply is kept throughout the identification process.
