On the French electrical grid, great part of the maintenance and repair are ensured by heliborne live line works. In order to continue its crucial activity, RTE have launched the development of a new STC which includes design and manufacturing new baskets.
For several years, the system of RTE has been handling a steadily rising number of requests for connecting new customers with photovoltaic or wind farms. Often, that is achieved by means of a branch connection to existing lines. Branch connections to lines reduce the cost of connection, but generate constraints in respect of the maintenance of structures, since the power supply to the customer cannot...
In the field of Standards, regulations and legal aspects it is important to underline the use of IEC and CENELEC standards used to protect the electrical worker against an Arc Flash. This presentation gives a practical overview of the standardization on the subject.
In this paper, we present our approach to embed data analytics into a maintenance process with a predictive approach, and provide an illustration on an industrial proof of concept around In-Flight Entertainment and Connectivity.
Huge energies being released in electric power equipment, there is a high risk for human injury due to electric fault arcs. Persons working at electric power equipment will have to be protected efficiently, particularly, if direct arc exposure is likely. Additionally to technical and organizational control measures, Personal Protective Equipment (PPE) may essentially contribute to prevent injuries...
Today there is an increasing number of DC applications where powerful DC fault arcs are likely to occur. These arcs are of potential risk for persons while working at the DC power equipment. DC arc conditions have not yet been analysed very well. There is a lack of information and detailed strategies on how to protect workers against short-circuits with fault arcs in DC power systems. Laboratory measurements...
Our live work training system addresses the need for developing the professional skills of HVB maintenance operators; thus, an employee initially trained to be a live work operator can develop towards the status of live work coordinator. Each initial training course has its own advanced training module, which helps meet the requirements of RTE and reinforce the skills of employees. Our training method...
This paper deals with the legal requirements to be met when low voltage live working is carried out by only one practitioner. According to these requirements, the possibility to implement first aid measures must be ensured at all times. Technical measures take priority over personal protective equipment (PPE) to ensure the safe implementation of work.
In a distribution network where medium voltage overhead lines are gradually replaced by underground cables, it becomes important to think about maintaining skills and professionalism of Medium Voltage Live Working activity, as recommended by French LW committee. We have to find a compromise between ensuring regular practice of all authorized persons, keeping enough authorized persons because of flexibility...
An interesting parallel has been discovered when studying the sources of quality and safety management in healthcare and carrying out of live working in the maintenance of electrical installations. The awareness and efforts of healthcare professionals focused on the increase in patient safety as well as the electrical profession in carrying out live working have a hundred year tradition. In both fields,...
SERECT regularly develops new innovative low voltage live working tools, in partnership with industrial companies. At the initiative of these developments there are two main sources of inspiration: First, original ideas from operators working in the field. And secondly the analysis by SERECT of accidentology, incident reports, and audits in the field. In both cases it is after analyzing the relevance...
The paper present the methods used in recent years in the national power grid to operate more efficiently as high voltage equipment. It includes shares of minor maintenance and operation undertaken by our company for management installations. It also briefly describes the results of applying new technologies and the technical analysis performed using such technical data. As part of asset management...
In case of the bare-hand method which is often applied especially during high voltage live-line maintenance, conductive clothing is the most important protective equipment to shield the extra-low frequency electric fields — acting as a Faraday cage. During the classification process of these clothing the screening efficiency is inspected besides some other electrical parameters: this shows the effectiveness...
Most live works carried out on distribution overhead lines require the displacement and support of conductors by means of: the assembly of hot sticks, or the jib of an aerial lift with insulating boom, or suspension pullers, or tension pullers. In order to ensure safe operations, it is essential to be able to assess the conductor stress and the loads on the tools and to verify that they do not exceed...
In France, grid live working is supervised by the Ministry of Labour and the Ministry of Industry. In the early sixties, both ministries together with transmission and distribution supply operators (TSO and DSO) decided to create the “Live Working Committee” to entrust all grid live work regulation. Nowadays, the Live Working Committee is in charge of defining work methods, tools and training programs...
This paper analyzes the main OSH international standars, the bases of continuous improvement and the principal aspects of Integrated Managemant Systems.
Whether in as much as the electric field is concerned it has been settled by the international scientific community since the 90's that there are no direct biological effects, only physiological effects caused by densities of the currents higher than 10 mA/sqm induced into the human body. When considering the impact of the magnetic component of the electromagnetic field of industrial frequency, the...
