Surge Protection Devices (SPD’s) are parallel connected devices whose sole purpose is to divert potentially damaging voltage transients to earth; thus preventing sensitive electronic equipment such as computers, control and communication equipment from being exposed to such voltages.

If you have surge protection device on site this will be checked by our engineers during the annual service visit and if it is found that the SPD has failed or absorbed a transient we are able to provide a quotation to replace this so the supply is kept fully protected.

Also if you do not have any Surge Protection, PFC Engineering can offer a full surge arrester survey, design and installation service that will be tailored to the specific needs of a client’s power system.

Surge Protection Devices (SPD’s) are now a requirement for all installations under Amendment 2 of 18th Edition Wiring Regulations. There are no exceptions permitted where over-voltage can cause

1. Serious injury to, or loss of, human life
2. Failure of a safety service
3. Significant financial or data loss
