30 April 2019 – The Swiss Army Knife of distribution Switchgear, the NOJA Power OSM Recloser, is today awarded with type testing certification to class C2 Capacitive Switching. This type test certifies NOJA Power’s flagship recloser system to switching capacitive loads up to class C2, in accordance with IEEE Std C37.66:2005, subclause 6.5. In securing this certification, the OSM Recloser is approved for service switching up to 600A.
In a testament to exceptional initial design considerations, the OSM Recloser required zero modifications from the current production model to achieve the capacitive switching ratings. All production 300 Series 16kA OSM Reclosers are capable of this level of capacitive switching.
“As voltage control on distribution networks is becoming more critical our utility customers are more often turning to capacitor banks on overhead distribution lines to manage this voltage control,” reports NOJA Power Group Managing Director Neil O’Sullivan. “Our OSM recloser provides an economical fully integrated solution for switching these capacitor banks.”
The NOJA Power OSM Recloser 300 Series 16kA model is now a standard replacement product or consideration for greenfield capacitive switching applications up to 27kV and 600A.
Achieving Class C2 capacitive switching with an autorecloser is no small task, with the test standards demanding arduous performance from the device. Among other tests, the test subject in this case must successfully interrupt 400 interruptions at 600A with a 10kA inrush at 6kHz. NOJA Power’s device successfully passed on all test requirements of the standard, and with certification secured field electrical engineers can be confident in the performance of this asset in the most demanding of environments.
