The dedicated metallic return conductor (DMR) of an HVDC transmission line may flashover as a consequence of a pole insulation failure, or may backflashover simultaneously with a pole during a lightning- induced event. This paper analyzes the transient voltage surges induced on the DMR of the Quebec-New England HVDC intertie by pole faults, and also evaluates the sensitivity of simultaneous pole and DMR backflashover probability to variations in line insulation and footing impedance.
