Under normal operating conditions, the protection relay is energized andthe contact is closed (X100:3-5). When a fault is detected by the self-supervision systemor the auxiliary voltage is disconnected, the contact X100:3-5 drops off and the contactX100:3-4 closes.Table 35:IRF contactTerminal DescriptionX100:3 IRF, commonX100:4 Closed; IRF, or Vaux disconnectedX100:5 Closed; no IRF, and Vaux connected5.3 Protection communication optionsTwo different protection communication options are available for the protection relay,that is, a fiber optic link and a galvanic pilot wire link.Multi-mode or single-mode glass fiber can be used in a fiber optic link. Select the requiredglass fiber mode when ordering the protection relay. Link lengths up to 2 km with multi-mode fiber and link lengths up to 20 km with single-mode fiber can be achieved. The fiberoptic cable used for protection communication is connected to the X16/LD connector inthe protection relay. See the technical manual for more information.If a galvanic pilot wire is used as a protection communication link, the pilot wire modemRPW600 is required. Select the pilot wire option when ordering the protection relay. Theprotection communication link always requires two modems in a protection scheme, thusdelivered in pairs of master (RPW600M) and follower (RPW600F) units. The protectionrelay is connected to the pilot wire modem using a single-mode fiber optic cable. Thus aSection 5 1MAC807603-MB AProtection relay's physical connections104 RED615 ANSIApplication Manual
