SEL-7202

Line Protection Panel

SEL-7202 configure-to-order (CTO) line protection panels provide the most advanced and fastest protection and control for two-terminal, two-breaker transmission lines using phasors and time-domain technology. Select between phase distance, line current differential, and traveling-wave protection relays to obtain the following features:

  • Fully redundant line current differential and/or distance protection
  • Main 1 line current differential and/or distance protection; Main 2 ultra-high-speed line protection
  • Pilot protection (DCB, POTT, or DCUB)
  • Direct transfer trip (DTT)
  • Overcurrent and directional elements
  • Breaker failure protection and reclosing for two breakers
  • Adaptive autoreclose cancel logic for hybrid lines
  • Sync-check
  • Trip circuit monitor
  • Local/remote operation for two breakers and one line switch
  • Hot-line tagging
  • Digital lockout and reset logic for two breakers (86BF1 and 86BF2)
  • Battery and breaker wear monitoring
  • Sequential Events Recorder (SER)
  • Load profile reporting
  • Traveling-wave-based fault locating and line monitoring
  • 1 MHz sampling event records
  • Built-in event playback testing
  • Reliable control power from multiple sources using the SEL-RPM Redundant Power Module
  • Dimensions of 92" tall × 28" wide × 28" deep
  • Customizable wire labels to match your existing nomenclature
  • Customizable nameplates for your nomenclature needs
  • Drawing package
