Mitigate blackouts and function more efficiently than ever before.
The Economy of Reliability and Efficiency
With the reliable control offered by SEL powerMAX systems, electric power providers and their customers reap economic rewards.
A powerMAX RAS allows bulk power grids to function closer to stability limits, operating transmission corridors at a higher capacity than ever before. In some cases, they can transmit over 50 percent more power across existing transmission lines.
The increase in efficiency allows you to meet rising demand without building costly new lines.
