CLOSE-RANGE PHOTOGRAMMETRY METHOD FOR SF6 GAS INSULATED LINE (GIL) DEFORMATION MONITORING

Abstract. Close-Range Photogrammetry (CRP) technology advanced rapidly along with the development of camera sensors. CRP has many advantages over other methods in terms technical data acquisition, product quality, and cost. Because these advantages, method can be used various applications. In this study, is to monitor deformation SF6 Gas Insulated Line (GIL) object between two substations Indonesian National Electricity Service Kuningan Barat, South Jakarta. Planning was carried out a simulation using 3D field obtained from reconnaissance process. During survey, photo collected smartphone processed form model. The produced configuration control points, check stations that have best Strength Figure (SoF) values. planning process, pre-calibration get orientation parameter values several experiments. results are next stage, namely acquisition processing. process for sessions. This done see changes coordinates occur Data processing by following classical photogrammetric stages. study average accuracy measuring which below tolerance 3 mm. With method, measurements quickly, accurately, at relatively lower cost than observation methods.
