SA Power Networks to trial eco-switchgear

SA Power Networks will be extending an existing partnership with Schneider Electric in order to make its grid operations more environmentally friendly.

The two companies will participate in a trial of Schneider Electric’s new SF₆-free pure air ring main unit (RMU). RMUs are switchgear used at the load connection points of a ring-type distribution network to feed a distribution transformer medium voltage to low voltage (MV to LV).

While SF₆ gas has been widely used in RMUs since the 1980s due to its superior electric insulation properties, it is 23,500 times more potent than CO₂, posing a significant threat to the environment.

The trial is part of SA Power Networks’ effort to remove harmful SF₆ greenhouse gases from its operations. The network operator, which distributes electricity to approximately 1.7 million customers in South Australia, will implement Schneider Electric’s RM AirSeT technology on its existing infrastructure, maintaining operational safety and reliability standards.

“This move to further transform our grid operations marks a significant next step forward in our efforts to provide a more sustainable network for our customers through establishing cleaner switching stations across the state,” said Aren Sears, Network Control Manager, SA Power Networks.

James Hunt, Vice President for Power Systems at Schneider Electric, said the company was delighted to be deepening its partnership with SA Power Networks.

“By unifying our expertise in energy management solutions with SA Power Networks’ commitment to sustainable solutions, we are proud to deliver this industry-first initiative to build a greener grid infrastructure,” he said.
