Western Power has said it will be delivering upgrades worth $700,000 to four Ring Main Units (RMUs) in the Mid West to help improve power reliability. The units - three in the Shire of Irwin and one in the City of Greater Geraldton - will be replaced with new units which will have automatic fault detection and remote switching capability. According to Western Power, this means the RMUs will be able to operate automatically, rather than requiring crews to attend, which will reduce the duration of outages significantly. Western Power Asset Management Executive Manager Gair Landsborough said the use of new technology was a key part of the operator’s strategy for improving power reliability. “RMUs help to balance the network by making sure voltage doesn’t drop, and to interconnect feeders, forming a loop in local networks so that we can restore power more quickly,” he said. “By using the latest technology, we can now automatically manage parts of the regional network, which is extremely beneficial.” Work is expected to begin later this month and be completed in early April. Western Power advises there will be power interruptions during the work, and those impacted will be notified directly.
