Commercial operation of the Pacific Northwest-Pacific Southwest Intertie through a 750,000 volt d-c two-wire transmission system is likely to begin in 1970. If successful, the technique will be rapidly adopted in widespread locations, creating a general threat of damage to buried structures by high amperage transient currents; pipelines present the most difficult portection problem. The Inter-Association Steering Committe was incorporated in Colorado to undertake research toward defining the problems, toward finding ways of measuring and predicting the effects of HVDC, and for perfecting a protective device for all buried structures. Meanwhile, prohibition of two-wire HVDC systems is sought unless the system is shut down completely when an emergency occurs, avoiding completely the flow of large currents in the ground; alternatively a three-wire system should be made mandatory.
