Research Facilities

The Associated Electrical Industries Ltd. comprises a group of independent companies concerned with the manufacture of prime movers, generators, power-transmission equipment and practically every kind of electricity-consuming device. The two largest of the group of companies are the Metropolitan-Vickers Electrical Co. Ltd. at Trafford Park, Manchester, and the British Thomson-Houston Co. Ltd. at Rugby. While there are research facilities in each of the companies of the group, research has until recently been concentrated very largely in the laboratories of the two main companies, the laboratories being separate autonomous bodies independently directed. Both these laboratories have been developed since World War I and both played no insignificant part in the last war. Accounts of each are being presented by Mr Churcher and Mr Davies. I should like to make brief mention of one matter about which there is frequent misunderstanding. It is often said that industry takes the best men from the universities, but my experience has shown that this traffic is in fact two-way. It is true that our companies take hundreds of young graduate engineers from universities all over the world, and of these a good selection is recruited to the research departments; but from our laboratories have also gone very many trained scientists into a large number of university positions, over a score into professorial chairs and senior positions throughout the government scientific services. It is my profound conviction that this flow in both directions is most desirable and should be encouraged as much as possible.

Measurement Practices

Electric power infrastructure, such as transmission lines or substations, is usually routinely inspected to assess its condition. The vast majority of typical defects in power transmission equipment manifests itself either through corona phenomena or through thermal effects. Therefore, an IR camera and a solar blind UV camera are sufficient for the detection of most defects in power transmission equipment. In the past, many network operators have relied mostly on manual inspections. In recent years, however, manned as well as unmanned aerial inspection methods, which are significantly more time effective, have become increasingly affordable and are therefore gaining in popularity rapidly.To obtain meaningful measurement results, many factors must be taken into account, which can even be difficult with conventional, static measurements. In the case of highly dynamic measurement practices (airborne or vehicle based), the combination of velocity and distance presents further challenges.This contribution is focused on the detection performance of UV and IR sensors under dynamic conditions. For this purpose, experiments were carried out with a typical IR and UV/corona camera at various distances to artificial defects. Additionally, a method for the automatic evaluation of UV und IR data based on machine learning is presented.

Simplified Calculation

In this paper, we propose a new method, namely equivalent condition score (CS) method, to calculate the failure rate of power transmission equipment with condition maintenance. Through the conversion of the CS evaluated after maintenance, we can investigate the effect of maintenance on the failure rate, and then calculate the failure rate of the equipment. The effectiveness of the proposed method is verified by field maintenance data. As shown in this paper, the equivalent CS method has a simplified calculation process and specific physical meaning.

The rural distribution network has deteriorated. This is due to the high failure rate of electrical equipment, high maintenance costs, reduced power quality, and the increased duration of power outages in agricultural production. This leads to a short supply of electricity, downtime of processing equipment, loss of production or production of low-grade products, as well as excessive energy losses during transmission. The important issue is the development of advanced methods for assessing the feasibility and effectiveness for component replacement of power transmission equipment with newer and more modern, reducing electrical energy loss in the distribution network. To solve these problems, various strategies have been developed and studied to improve the reliability of 10 kV overhead power lines by using modern insulators, wires, and supports.
