PHASE CURRENT
PHASE DIRECTIONAL 1(2)
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.
Figure 5–99: PHASE A DIRECTIONAL POLARIZATION
This element is intended to apply a block signal to an overcurrent element to prevent an operation when current is flowing
in a particular direction. The direction of current flow is determined by measuring the phase angle between the current from
the phase CTs and the line-line voltage from the VTs, based on the 90° or quadrature connection. If there is a requirement
to supervise overcurrent elements for flows in opposite directions, such as can happen through a bus-tie breaker, two
phase directional elements should be programmed with opposite element characteristic angle (ECA) settings.
