Multiple Australian Utilities approve the NOJA Power RC20 as a Power Quality Monitoring Device

NOJA Power OSM Recloser

When paired with the NOJA Power OSM Recloser, the RC20’s PQ monitoring permits the system to fulfil all distributed energy grid connection requirements with a single off-the-shelf product. This feat was previously accomplished through multiple assets.

Primary injection testing is used to verify the RC20’s Power Quality performance up the 63rd harmonic, mitigating commissioning costs and risk of non-compliance.

“Integrating PQ capabilities into an OSM Recloser allows connection engineers to halve the number of assets needed for a standards-compliant and type tested renewable connection installation,” says NOJA Power GM Sales Glen Harris.

“This integration also offers significant cost savings against the traditional approach of separate metering instrumentation and associated asset maintenance burden.”

The RC20 controller can be used in both the overhead network OSM Recloser application, or the underground cable connection GMK arrangement. With the approval in place, distributed energy connections can be made with a single type tested switchgear assembly.

NOJA Power’s OSM Recloser product has been used to connect many renewable energy projects to the grid. Some notable examples include the Kanowna Solar Farm connection near Moree Australia, and the Narromine Solar Farm operated by Neoen near Dubbo Australia.
