Directional power protection for reclosers

- Advertisment -

Switchgear engineering firm Noja Power has announced the addition of ANSI 32 directional power protection to the suite of features available in the RC10 and RC15 recloser controls for OSM reclosers. This functionality provides engineers with a new method for handling distributed generation protection requirements. Available as a free upgrade of firmware for field deployed NOJA Power RC10 and RC15 controllers, directional power is a core part of the new 1.25.0.0 firmware version for these devices.

The core operating principle of ANSI 32 directional power is to operate on calculated active power. This metric is then evaluated against the two cases, overpower and underpower. With these two cases considered, directional power helps protection engineers handle many protection cases, particularly:

  • Detect and operate against overloads
  • Under generation
  • Generator motoring
  • Motors acting as generators

With the global proliferation of distributed generation, alongside the OSM reclosers common deployment as distributed generation interconnection switchgear, ANSI 32 directional power plays an essential role in the global transition to decentralised generation.

Noja Power OSM reclosers are available in South Africa from RWW Engineering.
