Protection & Controls

A reliable protection & control (P&C) system is an absolute necessity. System faults must be isolated from the system in a dependable and secure manner for public safety and to minimize equipment damage and loss of load. Implementing a reliable P&C system comes with a cost, but to use the insurance analogy, there’s a balance to obtaining adequate coverage to protect the asset. Our engineers can expertly evaluate your requirements and standards to provide a recommendation for the most cost effective solution. For P&C of transmission lines, rotating machines, substations, distribution systems and all points in between, we have the experience.
