4 General Product Overview

Smart Wires’ SmartBypass technology is designed to protect other Smart Wires series compensation devices. The

SmartBypass does this by automatically activating switches to carry the transmission line current during line faults

or when operators desire to manually bypass the series compensation. The SmartBypass technology builds on the

protection used in other Smart Wires products, like the Power Guardian 390 which has internal protection on the

secondary side of its injection transformer. The SmartBypass is installed on a single-phase basis, meaning that for

most transmission deployments, there will be an equal number of units per phase.
