M-3410A Intertie/Generator Protection Relay

Facilitates standardization for small/medium intertie and generator protection applications.

  • Exceeds IEEE C37.102 and Standard 242 requirements for generator protection
  • Protects generators of any prime mover, grounding and connection type
  • Provides all major protective functions for generator protection including:
    • Out‑of‑Step (78)
    • Split‑Phase Differential (50DT)
    • Under Frequency Time Accumulation (81A)
    • Inadvertent Energizing (50/27)
    • Turn‑to‑Turn Fault (59X)
  • Expanded IPScom® Communications Software provides simple and logical setting and programming, including logic schemes
  • Simple application with Base and Comprehensive protection packages
  • Load encroachment blinders and power swing blocking for system backup protection (21) to enhance security during system abnormal conditions
  • Options:
    • Ethernet Connection
    • Field Ground/Brush Lift‑Off Protection (64F/B)
    • 100% Stator Ground Fault Protection by low frequency injection (64S)
    • Expanded I/O (15 additional Output Contacts and 8 additional Control/Status Inputs)

Protective Functions

  • Sync-check with Phase Angle, ∆V and ∆F with dead line/dead bus options (25)
  • Phase undervoltage (27) protection
  • Ground undervoltage (27G) protection
  • Dual-setpoint, single or three phase, directional power detection that can be selected as over/under power protection (32)
  • Dual-zone, offset-mho loss-of-field for generator protection (40)
  • Sensitive negative sequence overcurrent protection and alarm (46)
  • Negative sequence overvoltage (47)
  • Inverse time neutral overcurrent (51N)
  • Phase overcurrent with voltage restraint/control (51V) protection
  • Phase overvoltage (59) protection
  • Ground overvoltage (59G) protection
