(AP) 5-
• Fault/Event/Disturbance Records - Available from the serial communications or on the
relay display (fault and event records only).
• Distance to fault locator - Reading in km, miles or % of line length.
• Four Setting Groups - Independent setting groups to cater for alternative power
system arrangements or customer specific applications.
• Remote Serial Communications - To allow remote access to the relays. The following
communications protocols are supported: Courier, MODBUS, IEC 60870-5/103 and
DNP3.
• Continuous Self Monitoring - Power on diagnostics and self checking routines to
provide maximum relay reliability and availability.
• Circuit Breaker State Monitoring - Provides indication of any discrepancy between
circuit breaker auxiliary contacts.
• Circuit Breaker Control - Opening and closing of the circuit breaker can be achieved
either locally via the user interface / opto inputs, or remotely via serial
communications.
• Circuit Breaker Condition Monitoring - Provides records / alarm outputs regarding the
number of CB operations, sum of the interrupted current and the breaker operating
time.
• Commissioning Test Facilities.
1.2.3 Additional Features for the P442 Relay Model
• Single pole tripping and autoreclose.
• Real Time Clock Synchronisation - Time synchronisation is possible from the relay
IRIG-B input. (IRIG-B must be specified as an option).
• Fibre optic converter for IEC 60870-5/103 communication (optional).
• Second rear port in COURIER Protocol (KBus/RS232/RS485)
• 16 Logic Inputs - For monitoring of the circuit breaker and other plant status.
• Up to 21 Output relay contacts - For tripping, alarming, status indication and remote
control.
• Communication protocols available (ordering specification): K-Bus/Courier, MODBUS,
VDEW (IEC 60870-5-103), DNP3.0, IEC 61850 + Courier, IEC 61850 + IEC 60870-5-
