When compared to the conventional protection equipment all relays of the PROFESSIONAL LINE
reflect the superiority of digital protection techniques with the following features:
 High measuring accuracy by digital data processing
 Fault indication via LEDs
 Extremely wide operating ranges of the supply volt-age by universal wide-range power
supply
 Very fine graded wide setting ranges
 Data exchange with process management system by serial interface adapter XRS1 which
can be retrofitted
 Extremely short response time
 Compact design by SMD-technology
In addition to this, relay XR1 has the following special features:
 Detection of high impedance earth faults in rotor windings and is in two stage design.
 Short circuit and overvoltage proof measuring input for earth fault protection
 Separately setting of trip delay for R< and R<<
