Quality of Service and Economic Assessment of a MV Distribution Network Fault Locator

Abstract

The fault management process consists of several sub-tasks: fault location, fault isolation and service restoration. This work presents an assessment and evaluation of the practical aspects of the Medium Voltage (MV) Fault Locator at the Portuguese Distribution System primary substation. Eighty samples of incidents occurred at different MV network with different characteristics in Portugal were used to determine the time saving on the restoration process as well as the improvement on the quality of services indices. An economical assessment based of the use of the MV Distribution Network Fault Locator available in the Portuguese Primary Substation was done and discussed.
