FEATURES AND FUNCTIONS

4.1

CURRENT DIFFERENTIAL PROTECTION FUNCTIONS

Phase segregated current differential protection
Neutral current differential protection (optional)
2 and 3 terminal lines/cables
Feeders with in-zone transformers
Suitable for use with SDH/SONET networks (using P594)
GPS time synchronization (optional)
4.2

DISTANCE PROTECTION FUNCTIONS

Distance zones, full-scheme protection (6)
Phase characteristic (Mho and quadrilateral)
Ground characteristic (Mho and quadrilateral)
CVT transient overreach elimination
Load blinder
Easy setting mode
Communication-aided schemes, PUTT, POTT, Blocking, Weak
Infeed
Accelerated tripping – loss of load and Z1 extension
Switch on to fault and trip on reclose – elements for fast fault
clearance on breaker closure
Power swing blocking
Directional earth fault (DEF) unit protection
Out of step
Delta directional comparison - fast channel schemes operating
on fault generated superimposed quantities
Mutual compensation (for fault locator and distance zones)
Cross-country fault detection
64
InterMiCOM teleprotection for direct device-to-device
communication (optional)
4.3
