CHAPTER 5: SETTINGS
The trip output element is primarily used to collect trip requests from protection elements and other inputs to generate
output operands to initiate trip operations. Three pole trips only initiate reclosure if programmed to do so, whereas single
pole trips always automatically initiate reclosure. The TRIP 3-POLE and TRIP 1-POLE output operands can also be used as
inputs to a FlexLogic OR gate to operate the faceplate Trip indicator LED.
5.8.5.1 Three pole operation
In applications where single-pole tripping is not required this element provides a convenient method of collecting inputs to
initiate tripping of circuit breakers, the reclose element and breaker failure elements.
5.8.5.2 Single pole operation
This element must be used in single pole operation applications.
This element is used to:
• Determine if a single pole operation is to be performed
• Collect inputs to initiate three pole tripping, the recloser and breaker failure elements
• Collect inputs to initiate single pole tripping, the recloser and breaker failure elements
• Assign a higher priority to pilot aided scheme outputs than to exclusively local inputs
