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.

Protection functions

Directional overcurrent

Directional overcurrent combines an overcurrent operating condition with a direction criterion defined by the device and application. Its full name and suffix can distinguish phase and earth-fault implementations, measurement inputs and operating stages.

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

A distinction that matters

A 67 reference is not the same as directional power 32. Their quantities and operating criteria differ.

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.
