Refase™ is Synaptec’s powerful multi-zone power system protection solution, designed to protect complex, wide-area, or distributed networks and assets. The unique ability of Refase™ to simultaneously access many current measurements over a wide geographical area, or in multiple feeder sections within a substation, enables convenient centralised protection and control functions. This includes multi-zone protection and intelligent, highly-selective auto-reclose (AR or DAR), which is particularly suited to hybrid circuits composed of multiple underground cable and overhead line sections. Using Synaptec’s photonic sensing technology, granular unit protection of lines, cables, and other assets is enabled for complex, multi-ended and wide-area circuits that would are challenging and costly to protect using conventional measurement equipment.
