Side-by-side reference

Understand the difference.

Compare the meaning, drawing context and source references of two entries. A similar graphic or shared abbreviation does not establish equivalence.

First referenceCompare with

32R

Protection functions

Reverse-power protection

Detects active power flowing opposite to the defined generator or circuit direction.

Drawing use: SLD / Schematic
Application: Metering & protection
Reference family: IEEE / ANSI / Manufacturer

A distinction that matters

Reverse active power 32R differs from reactive-power flow 32V and must be distinguished in the trip schedule.

Protection functions

Directional power

Directional power protection uses the direction and magnitude of power according to the implementation and configured purpose. Reverse-power applications are one use encountered in generating systems; the generic device number does not specify the complete application.

Drawing use: SLD / Schematic
Application: Metering & protection
Reference family: IEEE / ANSI

A distinction that matters

Directional power and directional overcurrent measure different operating quantities. The numbers 32 and 67 are not interchangeable.
