Faster fault location
There are two main motivations for grid companies to find quicker ways of localising faults in the grid.
Every minute a grid company is not delivering energy to its customers, it is effectively losing money. This can be referred to as the cost of energy not supplied. Or CENS for short. Also, every minute spent localising a fault has a cost. Thus, faster fault localisation has a double reward.
CINELDI-partner Elvia has installed approx. 40 fault indicators in the 22kV network. The aim is to see if this reduces the time it takes to find the location of faults and the corresponding reduction in CENS.
Where old fault indicators had to be read manually, new indicators send digital signals allowing fault location to be performed centrally prior to dispatch of maintenance crew. In addition, increased safety and less strain on the components are expected as fewer test recouplings (to test if the fault is temporary or permanent) can be performed.
This pilot is a continuation of the IPN-project FASAD.
