ABB REF615C_C HCFCACABANB2AAN1XC

I. Basic Information


Model: REF615C_C | Order Code: HCFCACABANB2AAN1XC
Product Definition: ABB Relion®615 series Medium-Voltage Feeder Intelligent Electronic Device (IED). Configured per IEC Type C specification (Non-directional Overcurrent + Non-directional Earth Fault Protection). This all-in-one integrated relay integrates protection, measurement & control, energy metering, fault recording and communication functions. It is designed for 10kV~35kV distribution feeders, auxiliary power outgoing circuits and new energy grid-connection points, serving as a core replacement spare part for technical retrofits of existing power distribution systems in utility substations, petrochemical and metallurgical captive power plants.


Brand: ABB | Origin: Finland

Product Type: 4U drawer-type pluggable protection relay (modular front-display & rear-wiring structure, enabling unit replacement without system shutdown).
Compatibility: 10/20/35kV cable / overhead feeders, ring main units, package transformers, PV/wind farm grid tie-in points and industrial auxiliary power distribution systems; compatible with ABB SCADA and 800xA DCS power subsystem interface.
Mounting: Flush cutout installation on switchgear panel; Overall dimension: 177(H)×179.8(W)×201(D) mm, Net weight ≈3.9kg. Front panel IP54 ingress protection, rear terminal compartment IP20. PCB coated with Grade G3 anti-corrosion conformal coating complying with ISA71.04 standard to adapt to dusty and humid environments in chemical plants and power stations.
Standard Configuration: Large-size Chinese-language LCD + membrane function keys, local status alarm LEDs, rear terminal block (CT/PT analog terminals, digital input/output terminals), dual onboard Ethernet + RS485 communication ports and front-side USB service port.

III. Core Features


1. Comprehensive Relay Protection (Core of Type C Configuration)

  • Three-stage non-directional overcurrent protection (Instantaneous / Definite Time Instantaneous / Overload) + inverse-time overcurrent protection;
  • Three-stage non-directional earth fault protection (optimized for resistance-grounded or solidly-neutral-grounded distribution networks);
  • Thermal overload, PT fuse failure, CT open-circuit, circuit breaker failure, three-phase unbalance, under/overvoltage & underfrequency protection; User-defined programmable interlock logic configurable via PCM600 software.


2. Full-Scale Measurement & Energy Data Acquisition

Real-time sampling of three-phase current, voltage, active/reactive power, power factor, frequency and forward/reactive active & reactive energy; data readable locally via LCD and remotely uploaded to SCADA system; built-in daily & monthly energy freeze statistics function.


3. Fault Waveform Recording & Complete Event Logging

  • Fault Recorder: Captures full waveform of 8 cycles pre and post fault, exportable in standard COMTRADE format;
  • Event Logger: Stores ≥1000 millisecond time-stamped events (protection operations, status changes, alarms, parameter modifications); data permanently retained after power loss.


4. Dual-Redundant IEC61850 Communication

Dual Ethernet with PRP redundant architecture; seamless automatic switchover upon single port failure; GOOSE messaging enables inter-panel interlocking tripping complying with smart substation networking codes.


5. Full Hardware Self-Diagnosis & Local Alarm

Full startup self-test covering power supply, sampling circuits, trip output loops and communication chips; zone-divided front-panel LED indicators for fault, protection trip and communication failure; abnormal alarms automatically uploaded to master station; multi-level password access control to prevent unauthorized parameter modification.


6. Hot-Swap Maintenance Without Substation Shutdown

Drawer pull-out main unit with fixed rear terminal base; faulty unit replacement requires no field rewiring and can be implemented with switchgear live.


IV. Operating Principle


Power-on → Full power & hardware self-check → Load preset protection settings → Real-time primary electrical quantity acquisition via CT/PT;
Fault Trip Downlink: Line fault → Measured value exceeds threshold → Protection logic activation → DO relay drives circuit breaker opening, meanwhile fault timestamp and fault magnitudes are logged;
Data Uplink: Real-time analog & status data transmitted to substation master station / 800xA DCS via dual Ethernet or RS485;
Link Abnormality: Automatic switchover to standby Ethernet channel when one communication port fails, local alarm LED lit with corresponding status alarm reported to upper monitoring system.


V. Application Scenarios


  1. Feeder protection for outgoing bays of 10kV/35kV municipal urban distribution substations;
  2. Retrofit of 10kV auxiliary feeder protection for thermal power, petrochemical and coal chemical captive power plants;
  3. Measurement & protection for 35kV grid tie points and package transformer feeders of PV & wind power stations;
  4. Replacement spare relays for distribution ring network renovation inside metallurgy and cement heavy industrial facilities.
