| Another method of achieving savings is a voltage regulator. This is an active device, again fitted at your incoming supply but now with the ability to regulate the output voltages to your site (Fig.3). The benefits of this method over the previous are obvious. The output voltages are now controlled to a set level that can be adjusted on-line at site. Each phase has independent control allowing the output voltages to be balanced, improving motor efficiency. |

| This additional saving added to the saving by eliminating fluctuating voltages, out weights any cost advantage of the fixed ratio method. Due to the design of the Powersaver it is possible to continually reduce the output voltages to achieve the optimum setting for maximum savings while on-line. |
|
| A reasonably sized site can expect a swift return on investment for a voltage regulation unit. |
