Metering Devices, Protective Relays, Software and ConnectivityProtective Relays22.4DP-300DP-300 Current Differential Protection RelayProduct DescriptionThe current flowing in theindividual conductors ismeasured by means ofcurrent transformersinstalled on both sides ofthe protection zone. Thesetransformers form the limitsof the protection zone. Bymeans of freely configurablerelays, the unit will indicateif any of the adjusted faultcurrent limits have beenexceeded. The unit countswith a slope characteristicto prevent operation dueto CT ratio mismatches,CT ratio errors, CT saturationand errors because of tapchanges.For transformer applications,the unit has 2nd and 5thharmonic restraints toprevent misoperation in caseof inrush currents causedfor energization or overexcitation of the transformer.When used in transformerapplications, the DP-300allows you to change thephase shift of thetransformer, without havingto worry about changing theconnection of the externalCTs, via selecting the vectorgroup in the display. Thedifferent nominal currents ofthe high and low voltage sideof the transformer, as well asthe transformer ratio, may beconfigured. Every measuringpoint may be set separately.These features permit theDP-300 to be universal in itsapplications.The DP-300 permits designsimplification of theswitchgear cabinet, facilitatesthe commissioning, ensuresthe operation of the system,is user friendly and increasesthe availability of the system.ContentsDescriptionPageProduct Selection Guide . . . . . . . . . . . . . . . . . . . . . . . . . . . . 282FP-6000 Feeder Protection. . . . . . . . . . . . . . . . . . . . . . . . . . 286FP-5000 Feeder Protection. . . . . . . . . . . . . . . . . . . . . . . . . . 296FP-4000 Feeder Protection. . . . . . . . . . . . . . . . . . . . . . . . . . 304MP-3000 Motor Protection. . . . . . . . . . . . . . . . . . . . . . . . . . 312MP-4000 Motor Protection. . . . . . . . . . . . . . . . . . . . . . . . . . 322MD-3000 Motor/Generator Differential Relay . . . . . . . . . . . 328Digitrip 3000 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 331VR-300 Multifunctional Voltage Relay. . . . . . . . . . . . . . . . . . 341DP-300 Current Differential Protection RelayStandards and Certifications . . . . . . . . . . . . . . . . . . . . . . 346Technical Data and Specifications . . . . . . . . . . . . . . . . . . 346Dimensions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 348EDR-3000 Feeder Protection . . . . . . . . . . . . . . . . . . . . . . . . 350ETR-4000 Transformer Protection Relay . . . . . . . . . . . . . . . 361Ground Fault Relay . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 374Universal RTD Module . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 378IQ 125 Volt DC Power Supply. . . . . . . . . . . . . . . . . . . . . . . . 382Application DescriptionThe DP-300 offers a threephasecurrent differentialprotection for generators,motors and two windingtransformers, see Page 347.Features, Benefitsand Functions● True rms 6 x currentmeasurement, three-phasesystem on both sides ofthe protected zone● Secondary currenttransformer outputavailable as: /1A or /5A● Configurable trip setpoints for:● Differential current (Id)● Restrain current (Is)● Configurable delays● Four alarm relays● Three discrete inputs (forblocking, acknowledgmentand configuration)● Two-line LC display● Configurable transformerratio● Configurable vector group●Transformer inrushdetection/suppression● Individual configuration ofthe nominal current for thehigh- and low-voltage sideof the transformer●Configurable transformerratio separated for currentsof high- and low-voltageside of the transformer222222222222222222222222222222222222222222222222222222222222Volume 3—Power Distribution and Control Assemblies CA08100004E—December 2010 www.eaton.com 345
