The ABB DSPAD-02-647 is a stabilized differential relay designed for protecting two-winding power transformers and generator-transformers. 

Here are its key features:

  • Integrated Protection Modules:
    Three-phase differential relay
    Three-phase overcurrent relay
    Multi-configurable earth-fault relay
  • Winding Protection:
    Provides protection against winding short-circuits and interturn faults.
    Interwinding short-circuit protection for generators.
  • Earth-Fault Protection:
    Protects the transformer HV and LV side using various principles:
    Stabilized differential current
    High-impedance
    Residual current
    Neutral current
  • Overcurrent Protection:
    Three-stage overcurrent module for power transformers and generators.
    Two-stage backup earth-fault protection.
  • Fast Operation:
    Short operate time even with partial saturation of current transformers.
    Adaptable Operation:
    Differential relay module characteristics can be adjusted for different applications.
  • Stability:
    Stabilized against unwanted operations during faults outside the protected area and transformer inrush.
    Second harmonic restraint to prevent unwanted relay operations during transformer inrush.
    Fifth harmonic restraint for transformer overexcitation.

Additional Features:

  • Wide CT ratio correction range.
  • No interposing current transformers needed for two-winding power transformers.
  • Multiple output relays for circuit breaker tripping and signaling.
  • Integrated circuit breaker failure protection.
  • Disturbance recorder functions for analog and digital signals.
  • High immunity to interference.
  • CE marking for EMC compliance.
