ETSA Utilities has awarded NOJA Power Switchgear Pty Ltd a supply contract for the South Australian distribution networks 11-kV pole mounted, line reclosers requirements. Serving approximately 782,000 residential and business customers, through approximately 85,000 km of powerlines, ETSA Utilities is one of the largest distributors in the Australian national electricity market.

The NOJA power OSM15 recloser was selected by ETSA Utilities after a thorough engineering evaluation and selection process. Reliability and performance measures were key evaluation criteria applied by ETSA Utilities’ evaluating engineers. Desirable features offered in the NOJA OSM recloser include a high level of safety provided by the arc-fault controlled and vented, solid dielectric insulated design, and the robust 30,000 full load operations offered by the NOJA OSM recloser. The OSM reclosers will integrate to ETSA Utilities’ comprehensive network control and SCADA system via the DNP3 remote communications facility, provided within the RC01ES control cubicle. Some customized features were engineered into the OSM recloser and RC01ES design for ease of implementation into the ETSA Utilities’ working procedures.

NOJA Power are providing a number of value added services packaging a complete recloser, incorporating ETSA Utilities surge arrester and accessory requirements as well as specific mounting hardware which significantly reduce workshop assembly and testing hours for their staff.
