DPR-400 User Manual Rev_01 Firmware V-1.0DPR-400 is a state of the art, color screen,directional network analyzer and protection relay in144x144mm standard panel dimensions. Thanks toits low depth, it saves space in the panel. The devicecombines high precision, ease of use and versatilitywith a reliable and cost-effective design.The DPR-400 features dual current measurementcircuits, making it a class 0.5% accuracy analyzer,and a protection relay capable of measuring 50xIn.The DPR-400 offers various protection curves toprovide precise protection. Multiple protection curvescan be activated simultaneously.The DPR-400 displays multiple measurements on its4.3” screen. The large display offers ease of use andprovides abundant information.The device can connect to various Scada systemseasily via USB, isolated RS-485 and Ethernet portsfor remote monitoring.Modbus and IEC60870-5-103 protocols aresupported through RS-485 port.Modbus TCP/IP and IEC61850 protocols aresupported over the Ethernet port.Parameter configuration is done using the buttons onthe front panel or with the free PC software. Theprogram connects via USB, RS-485 or optionallyover the Internet. Additionally, firmware updates areperformed through the USB port.Two of the relay outputs of the device haveconnection monitoring capability. These outputscontinually check the integrity of the load circuit, andraise an alarm if the circuit opens.DPR-400 stores up to 7 oscillographic records inCOMTRADE format in its 1MB internal memory.The device meets the security, EMC, vibration, andenvironmental standards for industrial products.DPR-400PROTECTION RELAY• 4.3” color graphic display, 480x272 pixels• Accurate power analyzer (%0.5)• 4 quadrant energy counters• Multiple protection curves• Self-test, internal failure monitoring• Cold reclosure• Configurable digital outputs• Configurable relay outputs• 3 independent adjustment sets• Multiple languages• All parameters front panel adjustable• 3 level password protection• Free PC program for setup• Setup through USB, RS-485, and Ethernet• 14 x configurable front panel leds• Manual & Scada driven closing and opening• Firmware upgrade through USB• IP65 protection (with optional gasket)• Low panel depth, only 55mm• Trip counter, service warning• IEC Normal, Very, Extreme Inverse• UK Long Term Inverse,• IEEE Medium, Very, Extreme Inverse• US Normal Inverse, Short Time InverseANSI CODE DESCRIPTION27 Under Voltage (Ph-Ph / Ph-N)46 Negative Sequence Overcurrent46BC Broken Conductor47 Negative Sequence Over Voltage49RMS Thermal Overload50,51 Overcurrent50N/51N Ground Overcurrent50BF Breaker Failure59 Over Voltage (Ph-Ph / Ph-N)67 Directional Overcurrent74CT CT Supervision79 Reclosure81O High Frequency81U Under FrequencyCLP Cold Load PickupDESCRIPTIONPROTECTION FUNCTIONSPROTECTION CURVESFEATURES
