Directional reactive-power protection
Supervises forward or reverse reactive power using the selected relay's power-direction convention.

What it represents
Supervises forward or reverse reactive power using the selected relay's power-direction convention.
The drafting record should connect this function to the CT/VT measurement pairs and reactive-power sign reference, then trace the reactive-power alarm or operating output. Keep the complete designation and equipment tag together so that the SLD, relay logic and terminal schedule describe the same implementation.
The cited mapping is a public manufacturer example (Eaton ETR family). Suffixes are not universal equivalences across products, and this reference supplies neither a protection setting nor certification of the selected scheme.
How to read it
- Identify the CT/VT measurement pairs and reactive-power sign reference.
- Trace the reactive-power alarm or operating output.
Information to show or reference
- Label the CT/VT measurement pairs and reactive-power sign reference.
- Cross-reference the reactive-power alarm or operating output.
- Retain the complete suffix, selected device tag and manufacturer manual revision.
A distinction that matters
In the cited Eaton devices 32V denotes VAR protection; V is not a universal indication of a voltage-only function.
