Overview of ABB REC670 Bay Control Unit:

  • Functionality: Control, protection, and monitoring of various types of bays in power networks
  • Application: Especially suitable for control systems with distributed control IEDs in all bays with high reliability requirements
  • Voltage Compatibility: Can be used up to the highest voltage levels
  • Suitability: Applicable for controlling all apparatuses in any type of switchgear arrangements

Basic Data:

  • Current Transformer Ratio:

    • For 2000/1 A CT: Used for high-current measurements, ratio of 2000 primary amps to 1 secondary amp.
    • For 100/5 A CT: Used for lower-current measurements, ratio of 100 primary amps to 5 secondary amps.
  • CT Class:

    • For 2000/1 A CT: Class 5P20, indicating a 20 VA burden and 5% accuracy class.
    • For 100/5 A CT: Class 5P20, indicating a 10 VA burden and 5% accuracy class.
  • Secondary Resistance:

    • For 2000/1 A CT: 6.2 ohms
    • For 100/5 A CT: 0.26 ohms
  • Cable Loop Resistance:

    • For 2000/1 A CT: Less than 100 m (2.5mm^2), resulting in a resistance of 0.8 ohms at 75°C.
    • For 100/5 A CT: Less than 50 m (2.5mm^2), resulting in a resistance of 0.4 ohms at 75°C.
  • Max Fault Current:

    • For both CTs: Limited by switchgear rated fault current, with a maximum of 40 kA.
  • Note:

    • Cable loop resistance is kept low to limit the voltage drop and ensure accurate measurements.
    • In case of high earth-fault current, a two-way cable may be necessary.
    • The maximum through fault current is limited by reactor reactance, with inrush typically around 800 A.
