EMP Protection

Electromagnetic Pulse Protection for the Grid

Electromagnetic Pulse (EMP), such as that produced by a vehicle-mounted EMP device, can disrupt, damage, or destroy electronics in the electric grid communication and control systems. For instance, most critical assets such as relays and communication lack protection measures for high voltage spikes. The substation control house provides some protection measures against events like lightning strikes, but an EMP event will spike 5 to 10 times greater voltages and induce localized currents beyond the capability of typical lightning countermeasures.

Doble’s EMP solutions consist of integrated 19” standard racks with a system of mounting shelves and brackets that can enclose nearly any equipment. Doble EMP Protection racks can house active equipment with optical feeds to the yard, or filtered data conductors. Backup equipment can also be stored on site in the EMP protected vault, ready for technicians to arrive and begin recovery work.

Our products are certified “Hardness Critical Items” (HCI) by Little Mountain Test Facility, a state-of-the-art test center, and U.S. Air Force Materiel Command laboratory dedicated to simulation testing of nuclear hardness, survivability, reliability, and electromagnetic compatibility of defense systems.
