Feeder Protection RelayREF 610Fig. 3 Substation feeder O/C and E/F protection, and substation busbar protection based onRE_ 610 series protection relays. The operate time of the busbar protection has beenspeeded up using the principle of upstream interlockingThe connection of the CTs to the REF 610relay depends on the available number andtypes of CTs in the feeder cubicle. Generallyan outgoing feeder is equipped with threephase current transformers for high- andlow-set overcurrent protection. The residualcurrent for the earth-fault protection can bederived from the three phase currents. It canalso be measured with a ring-type cable currenttransformer, should the outgoing feederbe a cable line and a sensitive earth-faultprotection be required.Should the feeder cubicle be equipped withtwo phase current transformers, the REF 610relay can still be used for high- and low-setovercurrent protection including phase discontinuityand phase unbalance protection.ABB

Feeder Protection RelayREF 6101MRS75629513. Mounting methodsUsing appropriate mounting accessories thestandard relay case for the RE_ 610 seriesrelays can be flush mounted, semi-flushmounted or wall mounted. The flush mountedand wall mounted relay cases can alsobe mounted in a tilted position (25°) usingspecial accessories.Further the relays can be mounted in anystandard 19” instrument cabinet by means of19” mounting panels, available with cut-outsfor one relay or two relays. Alternatively, therelays can be mounted in 19” instrumentcabinets by means of 4U Combiflex equipmentframes.For routine testing purposes the relay casescan be equipped with test switches typeRTXP 18 which can be mounted side by sidewith the relay cases.Mounting methods:• Flush mounting• Semi-flush mounting• Semi-flush mounting in a 25° angle• Rack mounting• Wall mounting• Mounting to a 19” equipment frame• Mounting with a RTXP 18 test switch toa 19” rack14. Relay case and relayplug-in unitAs a safety measure the relay cases for thecurrent measuring relays are provided withautomatically acting contacts for shortcircuitingthe CT secondaries when a relayplug-in unit is withdrawn from the relay case.In addition, the relay case is provided with amechanical coding system preventing currentmeasuring relay plug-in units from being insertedinto a case for a voltage relay unit andvice versa, i.e. the relay cases are associatedto a certain type of relay plug-in unit.There is, however, an universal relay caseavailable, which is not associated to a certainplug-in unit type. When a relay plug-in unitis plugged into such a relay case for the firsttime the relay case will automatically adaptto that particular relay type, i.e. the shortcircuitingcontacts will be activated as willthe mechanical blocking system. Hereafterthe relay case is permanently associated to acertain relay type. Fig. 4 Flush mounting Fig. 5 Semi-flush mounting Fig. 6 Semi-flush mountingin a 25° angleABB 17
