摘要

The objective of this project was to develop and commercialize a system to automate therncollection of cathodic protection (CP) data. This objective was successfully met. KeySpanrnEnergy and the GTI Sustaining Membership Program (SMP) jointly funded this project. Therninitial device specification was tailored to the needs of the Brooklyn Union (BU) distributionrnterritory, an area predominantly protected by galvanic cells consisting of buried sacrificial anodesrnconnected to the pipe.rnThe BU procedure required for a CP data reading was to take a pipe-to-soil potentialrnreading with respect to a reference cell placed in contact with the soil. This reading is taken withrnthe sacrificial anode connected and then disconnected. The current from the anode whilernconnected is also taken. The initial prototypes performed these functions and provided thernadditional function of deriving a power supply from the anode current.rnThe initial prototypes, deployed in 1997, showed several shortcomings. The packagingrnneeded modification to provide greater longevity in the buried environment. The anode-derivedrnpower supply required a certain minimum corrosion activity to operate the CP monitor. Thernpermanent burial reference cells originally used were expensive and also had longevity issues.rnDuring the project, Brooklyn Union became part of the larger company, KeySpanrnEnergy. This, combined with the above issues, led to a reevaluation of the product specification.rnThe CP practices of the SMP membership were also surveyed in an effort to capture thernspecification for the broadest market. Commercial manufacturers for many of the keyrncomponents were identified and engaged. New prototypes were fabricated and tested with muchrnbetter results.rnThe most recent version of the CP monitor is under beta test with Peoples Energy ofrnChicago. The current version is a direct-burial transponder that is connected to the main and arnreference cell. It is located and read with a handheld device from above ground. Location andrnreading functions are both wireless, requiring a short-duration visit to the transponder location.rnThe CP data from the transponder is stored in a Palm PDA for display and transport from the fieldrnback to the utility.rnThe commercial version of the wireless CP monitor will be manufactured and distributedrnby Borin Manufacturing LLC. Borin is the world’s largest provider of permanent burial referencerncells, one of the critical system components. A battery with a life expectancy of 15 years willrnpower the commercial system. Samples of the system fabricated in Borin’s Los Angeles facilityrnare currently undergoing beta testing.
