PATH: SETTINGS
GROUPED ELEMENTS
SETTING GROUP 1(6)
PHASE CURRENT
PHASE DIRECTIONAL 1
The TARGET setting is not user-selectable and forced to "Disabled". If Targets are required from directional
elements, it can be achieved by assigning directional element output to a digital element, where targets
selection can be used as required.
The phase directional elements (one for each of phases A, B, and C) determine the phase current flow direction for steady
state and fault conditions and can be used to control the operation of the phase overcurrent elements via the
BLOCK
inputs
of these elements.
