ABSTRACT:
An apparatus for powerline designing and maintenance which provides assistance for the initial design of overhead powerlines and their maintenance. The apparatus includes a device for measuring the initial ground profile along a proposed route, and for defining the required support structures, taking into account the predicted cost of components together with prevailing safety standards and industry guidelines. Facilities are also provided for ordering fittings and for checking line tension at the construction stage. Previously constructed lines may be monitored by visual inspection of existing fittings for depreciation and damage or by resurvey and the data gathered can then be compared to the original design specifications.
