Product Description

Multilin L90

Line Current Differential System

The L90 provides high-speed current differential protectionsuitable for transmission lines and cables of various voltage levels, whilesupporting complete distance protection and dual-breaker applications suitablefor single and three-pole tripping applications. The L90 uses synchronizedsampling at each relay to limit the impact of communications channel issues.The differential element's adaptive restraint balances sensitivity for internalfaults and security during external faults. The L90 supports inter-relayprotection communications via direct fiber as well as different interfaces.

Applications

  • Overhead lines including series-compensated lines and underground cables of different voltage levels
  • Circuits with tapped transformer feeders
  • Suitable for three-terminal line configurations, with channel redundancy and direct transfer tripping (DTT)
  • Wide area system monitoring and control and using integrated protection and synchrophasor measurement
  • Single and dual-breaker circuits requiring single/three-pole autoreclosing and independent synchrocheck supervision
  • Secure application with Capacitively-Coupled Voltage Transformers (CCVTs)
