Overhead Line Survey

An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy across large distances.

Similar in scope to a topographic survey, an overhead line survey focuses on creating an accurate and detailed ground profile.

This survey is crucial for determining the exact undulation of a parcel of land, knowledge that is, in turn, critical in the design of new or refurbished/rebuilt power lines.

Accuracy must be a key feature of overhead line surveying, as power lines must comply with statutory clearance requirements. Line Design Technology Limited employs various methods, including survey-grade receivers, to produce precise survey results.

The finalised overhead line survey can then be used to create compliant route plans.

Whats the process?

Using either a Survey-Grade GPS or Total Station, the Surveyor will establish the Power Line route. Then the Surveyor will record all ground and vertical features within the survey swath. This data will be used to produce a line profile by the line designer.

What kit do we use?

Our Company Surveyors are all equipped with Sokkia Total stations as well as Carlson BRx7 GNSS receivers.
