The US Department of Energy estimates that electrical infrastructure problems cause 10% of wildfire ignitions across North America. According to Electrek, Hitachi Energy recently debuted its wireless Spark Prevention Unit (SPU) indicators to aid the existing problem on November 30, 2022.
“Our innovation is driving grid resiliency by safeguarding the network’s key assets. By mitigating the risk of wildfires ignited by power lines, we are protecting communities, wildlife and the environment.”

SPU indicator’s functions
The grid can be “remotely” monitored by utilities thanks to the new Wireless SPU Indicators from Hitachi Energy. Interestingly, this innovative function is enabled by its automated visual inspection rounds.
Furthermore, surge arresters’ thermal and current loads are regulated by the SPU. When built in wildfire-risk locations, it shields equipment from outbursts in the power grid.
The SPU also stops the current flow and disconnects the surge arrester in the occurrence of a grid thermal overload. That said, the circuit is kept from becoming overloaded and overheated. Additionally, it inhibits hot particles from ejecting into the air that may otherwise spark a wildfire.
Another remarkable feature of the said technology is that it alerts the utility field team when it needs to be replaced.
“We continue to pioneer technologies to advance the world’s energy system to be more sustainable, flexible and secure – for today’s generations and those to come.”
