ABSTRACT

Urban infrastructure systems, such as electricity networks, are the backbone of modern societies. In Sri Lankan context, the electricity network plays the most vital role in ensuring the smooth function of almost all the socioeconomic systems. The distribution network of Sri Lanka is almost all overhead, operates in medium voltages of 33 and 11 kV and a low voltage of 400/230 V. Feeder line inspection is essential for an electrical distribution utility for operational and maintenance purposes in both planned maintenance and breakdown clearing. Commonly used current inspection methods are people online method, telescope, and using a helicopter for inspections. Broken strands, bulk shares, surface corrosions, and conductor splits can be detected from the CCD camera, which has been used to identify those surface geometric failures of conductors and optical cable. Vibrating structure gyroscopes are known as MEMS (micro-electromechanical systems) devices, which have the ability to operate under the Coriolis force fundamentals.
