Industrial Systems
Features and Benefits
Robust features put the L90 ahead of the competition:
• Innovative current differential scheme features adaptive restraint
• Programmable FlexLogicTM reduces device costs and simplifies wiring
• Non-volatile flash memory allows easy field upgrades
• Common draw out modules reduce spare part costs
• Charging current compensation for long lines or cable applications
• Channel asymmetry compensation (up to 10miliseconds) via
Irig-B port (GPS)
Scalable, flexible features that increase reliability

Industrial Systems
Additional Features
• Cost-effective (up to 250 Microsecond) time synchronization for
communications
• The L90 can synchronize and start protecting the line within 10 seconds
• A fine-tuned frequency tracking mechanism increases accuracy of the
relay’s measuring and protection functions under off-normal frequency
conditions
• User-programmable pushbuttons for
secure and reliable custom control
One of the best line current differential protection systems in the world

Industrial Systems
Monitoring and Metering
• Fault location and reporting – stored in non-volatile memory
• Breaker Arcing Current (I 2t) – for maintenance on breaker wear
• User-programmable oscillography – data viewable via URPC software
and can be stored in the oscillography record or data logger
• User-programmable data logger – captures events and time-stamps
them for use with fault analysis
• Trip circuit monitoring
Built in monitoring and metering open a window into your system
