Detection of power line insulators on digital images with the use of laser spots
2019
The massive growth of technologies used to register and process digital images allow for their application in evaluating the technical condition of power lines. However, it is not possible without a set of dedicated methods for obtaining diagnostic information based on registered video data. The method described here details the detection of power line insulators in digital images featuring diversified backgrounds using laser spots. The algorithm of detecting an insulator in analysed images is based on testing the digital signal of pixel intensity profiles read between subsequent pairs of laser points in the image. The method is comprised of the following stages: import the image with laser…
Fibre-Optic Links For A Measurement And Control System At A HV Laboratory
1990
The paper presents a fibre-optic linking system for a measurement and control system installed at an industrial HV laboratory. The indirect voltage and current measurement system is furnished with the E0/0E transducers and FO links. The exploitation requirements on the adequate measurement accuracy and reliability have necessitated the inclusion of additional, digital PO link feedback from the computer control system. The proposed measurement system with the FO link has been installed at an HV laboratory transformer of an electric power station and successfully tested together with the overall equipment.
Fiber - Optic Loop Network With Active Nodes For An Electrical Power Plant
1990
This paper presents a fiber optic loop network for a measurement and control system of an electric power plant. The network consists of the central computer terminal, the set of specially distributed digital FO links and local station installed at the important power facilities. The well-known FO link advantages contribUte to high reliability and safety of work of the system. The operation of the loop network, treated as an autonomous one, is controlled by a microcomputer system. Transmission protocols and the cooperation with the local station are also described. The proposed loop network model is illustrated with an example of the laboratory - scale system.
