Why Sensors?
Smart sensors – the foundation of a modern power grid
Energy supply is becoming increasingly complex: solar panels, wind power, and batteries feed electricity into the grid in a decentralized way. Traditional measuring devices located only at the generator side are no longer sufficient.
Our solution
Greenwood-Power sensors reliably monitor the grid — at medium and low voltage levels — and provide the data essential for an efficient smart grid.
