Where do surges come from?

Externally generated surges are the most destructive and account for nearly 30% of all disturbances. The most obvious, and dramatic source is lightning. Although lightning is the most destructive, it is actually the least common. The most common source of externally generated power surges is the electric utility company itself.

The powering up and down of different internal components (generators, motors, etc.) also creates surges that are distributed throughout the electrical systems. These internally generated power surges can come from a number of sources and account for almost 70% of disturbances.

What is the solution?

APT carries a full line of 3-phase hard-wired and DIN Rail mounted SPD’s (surge suppression devices) to address the many different wind turbine applications. These applications can vary from a 24V hub to a 398V/690Y transformer. APT’s full line of SPD’s will allow for a total surge protection solution at all vital points.
