How to Upgrade to an RC-20 Controller

NOJA Power’s flagship Recloser Controller, the RC-20, is now a globally available control option for the OSM Recloser.

Bringing Synchrophasors, High Resolution Data Capture and Power Quality recording up the 63rd Harmonic, the system is designed as a single control platform for distributed generation connections and advanced smart grid implementations. The RC-20 is also compatible with the award-winning NOJA Power Analytics, a cloud infrastructure implementation for harvesting and analysing Synchrophasor Data.

“Our existing customers and installations can easily upgrade from RC-10 or RC-15 controls to RC-20 by simply replacing the existing control,” reports NOJA Power Group Managing Director Neil O’Sullivan.

“With the onboard 4G modem the RC-20 control can interface to the customer SCADA using their existing communications medium and separately and securely interface to the NOJA Power Analytics Cloud to stream synchrophasor data or even stream synchrophasor data directly to the utilities Cloud solution.”

Existing installations of NOJA Power OSM Reclosers with RC-10 or RC-15 controllers can be easily upgraded to the RC-20 Control. All existing protection and automation functionality is available in the RC-20 alongside the new RC-20 only features.

The Control Cable Connection is universal across these products. Upgrading to the RC-20 simply involves a Low-voltage-only controller replacement. The existing installation control cable and LV supply connection can be reused to connect an RC-20.

The upgrade to the RC-20 also provides a new warranty for the control system, along with access to future system upgrades planned for the NOJA Power Recloser Control platform.
