Ground Mount Kiosk
Solve Medium Voltage Network Connections with a single device.
A modular, highly customizable circuit breaker kiosk designed to protect underground networks.
Examples of the Ground Mount Kiosk's versatility to address any Underground Network Protection Challenge.
Solar Farm Connection
The Kanowna Solar Farm was connected to the MV distribution grid with the NOJA Power GMK, allowing the asset developers to address all connection requirements with a single, factory tested product.Learn More
Auto Changeover for Critical Supply
Two NOJA Power GMK's serve the rail electrification supply with a fibre-optic connected auto changeover scheme running between the units, providing an added layer of supply reliability for critical infrastructure.Learn More
This GMK installation provides electrical protection and control for one of Australia's largest mining projects in WA's Pilbara region. The integrated protection functionality of NOJA Power's RC-10 Control in this assembly provides safe and reliable power for this critical infrastructure project.Learn More
Waste Gas Generator Connection
Located in Western Sydney, this NOJA Power GMK was used to connect a gas turbine generator powered by recovered methane from landfill. This installation included generation metering, remote control and monitoring.
Infrastructure Connections to Existing Overhead Assets
The POWINS-NOJA Power Mobile Substation facilitates planned infrastructure operations that have a requirement to “take from” or “export to” an existing overhead service. The NOJA Power GMK provides a 15 kV OSM Recloser and load side interlocked earthing switch in an environmentally resilient assembly.Learn More
Battery Storage Connection to MV Distribution Grid
5 MW of Tesla Battery Energy Storage equipment were connected to the medium voltage distribution grid through a NOJA Power GMK. This system improves the networks’ ability to integrate more renewable energy by improving system strength for asynchronous generation.Learn More
Photovoltaic (PV) & Battery Storage Connection
The GMK3000 and RC-20 controller provides both conventional protection and utility Power Quality monitoring. The GMK4000 houses two NOJA Power OSM units configured as Circuit Breakers complete with RC-10 controllers. Having two circuit breakers allows load shedding under a switching agreement with the local utility.Learn More
Protection of Underground Cables
NOJA Power’s GMK product provides DIN taper bushings for direct underground cable terminations onto the device. The segregated nature of the GMK design also splits the device into three separate compartments – the Cable Bay, the HV cabinet with Switchgear and the Low Voltage Instrument Panel.
Factory Tested to the most rigorous industry standards.
The GMK allows for a fully specified and encapsulated switchgear arrangement to be built and tested in the clean room environment of the state of the art NOJA Power manufacturing campus in Brisbane Australia.
GMK-1000 Series Kiosks
Compact GMK-1000 series, to 27 kV with a 1.1m x 1.1m footprint.
GMK-2000 Series Kiosks
Highly Customisable GMK-2000 series, rated to 38kV with options of Earth Switches, Revenue Metering, Power Quality Metering or more.
GMK-3000 Series Kiosks
Highly Customisable GMK-3000 series with Internal Arc Classification, rated to 38kV with options of Earth Switches, Revenue Metering, Power Quality Metering or more.
GMK-4000 Series Kiosks
Also known as the Auto-Changeover GMK, this design provides two NOJA Power OSM Reclosers within the same Ground Mount Kiosk Enclosure.
This design topology is applied in two primary cases:
- Supply Critical Load from Two Alternative Sources
- Renewable Energy Connection
