Different customer needs within a particular service area warrant different FLISR approaches. All utility customers would appreciate improved reliability from fewer and shorter interruptions, but only select commercial and industrial (C&I) customers experience major losses during an interruption. For these customers, a simple FLISR restoration isn’t fast enough. According to IEEE, an interruption of 10 cycles can cause production and motors at some factories to halt and require restarting. Just one of these interruptions can cost a C&I customer hundreds of thousands or even millions of dollars in lost production or revenue.
