Ideally, every electrical panel should
be surge protected. However, this
may not be practical or feasible.
Proven surge protection practices
do not have to be complicated or
costly. All you need to do is
address the following:
1- Where should hard wired
SPDs be installed on the
electrical system?
2- What size and type SPD
should be used?
Surge Protecting a Wind Farm
Service Entrance
Applying surge protection at the service interconnect “Stops Surges Before They Get In” from the utility grid. The best location to apply surge protection is on the low voltage side of the 690/20000 V step up transformer. SPDs installed at this location are recommended to include integral disconnects for ease of servicing.

Outside Loads
SPDs should be installed at distribution panels feeding nacelle control cabinets, inverters, etc. to prevent back feeding surges from entering the main building.

Lower Voltage Panels
120V circuits need SPDs to condition residual surges leaving the service entrance SPD as well as any internally generated surges. Examples could be motor controllers, control panels, or any other panel powering sensitive electronics.

Individual Equipment
If surge protection is applied at the previous locations, redundant protection maybe warranted for sensitive, costly equipment. This may include anemometer, obstruction lighting, etc.

Data Lines
Security, fire alarm, and telephone systems using copper communications lines need protection especially for communication circuits including PLCs, modems, and PCs.
