Equipment can be purchased as a Full set or as a Basic Set. All DC Voltage Gradient Equipment Sets come with spares and is manufactured in UK to military specifications. A FULL set comes complete with everything except a DC power source needed to survey a buried pipeline. The equipment which is a direct descendant from the original work carried out in Australia is packed into protective carry cases and has two main components, the Interrupter and the Survey Meter. During manufacture maximum emphasis has been placed on simplicity, quality and robustness of construction with the equipment kept as flexible as possible to use. Although the equipment comes with an instruction booklet, a very comprehensive training course is available to ensure operators know how to gather data and to use and interpret results in order to gain maximum benefit from the technology transfer process. The Basic Set consist of the same quality components but the mimium components required to do DCVG Surveys. There are no carry cases or spares in a BASIC set.
For pipelines with multiple rectifiers, we recomment the purchase of Satelllite Controlled Synchronous Interrupters so all rectifers are switcing ON/OFF at same time.
