  2. What is it? • Generator Protection System based on the successful 851/951 platform • Includes Multifunction Protection and: • Metering and Control • Relay Status Alarms • Breaker Monitoring • Detailed Event and Oscillography Data • Communication (Status, Metering, Control, Settings, Events) • Programmable Logic • Programmable I/O

  3. What makes it unique? • High Flexibility • Flexibility in protection settings • Flexibility in application logic • Flexibility in packaging (H1 and S1 case) • Optimal functionality in a small package

Time • Use for Inadvertent Energization logic or • Ground fault protection or • User-defined purpose

  8. Protection - Current • 51N monitoring Optional Independent Ground Input can act as OC differential. • For those applications requiring Generator Differential (87): Use the BE1-87G or the BE1-CDS220 • Redundancy gained by placing the differential in a separate package avoids the “all your eggs in one basket” pitfall • Basler offers competitive pricing for the CDS220/GPS100 combo package
