The BE1-CDS220 Current Differential Protection System is a 3 phase, 2
restraint multifunction, numerical relay that provides percentage restrained
differential protection along with overcurrent, breaker failure, control, metering,
monitoring, and alarm functions in an integrated system.
• All versions include harmonic restraint as well as phase shift and tap
compensation for use in transformer applications. Detailed current check report
provides record of proper CT connections.
• Includes frequency compensation for high accuracy in generator and motor
differential applications.
• BESTlogic provides the user with complete flexibility in configuring a protection
and control system. User programmable variable and switch names make the
CDS relays completely self-documenting.
• Each CT circuit is low burden and isolated to allow improving zones of protection
with fewer costly CTs.
• Optional programmable LCD display allows the relay to replace local indication
and control functions such as panel metering, alarm annunciation, and control
switches.
• Three independent communications ports with protocol support allow integration
with distributed control systems.
• The CDS220 is available in horizontal and vertical configurations to provide cost
savings in any installation. The CDS220 is fully drawout and fits cutout, drilling,
and behind-panel projection dimensions for common Basler Electric, GE, and
Westinghouse differential relays.
