Among the maintenance operations, insulator washing is of particular interest especially in those regions where the pollution is very high such as coastal areas, desert regions and others. These operations can be classified as environmentally hostile and would benefit from the introduction of robotic equipment. HV Robotics, a branch of Cooperativa Ceramica Industriale Livorno, has developed and tested in its HV laboratories a hot line insulator washing device that works in close proximity of the insulator surface; the washing head works at the potential of the insulator. The washing principle is based on the action of high-pressure water jets emitted by nozzles, which move following a path that guarantees that the jet reaches even the most inaccessible parts of the insulator. This method makes for a more uniform and effective washing action, as well as for a much lower water consumption as compared with methods based on nozzles placed at earth potential, located far from the insulator. The washing device is described.","PeriodicalId":328713,"journal":{"name":"ESMO '98 - 1998 IEEE 8th International Conference on Transmission and Distribution Construction, Operation and Live-Line Maintenance Proceedings ESMO '98 Proceedings.

These systems have been developed with interfaces into supervisory control and data acquisition (SCADA), automatic meter reading systems (AMR), utility call centers, customer information systems (CIS), and an automated mapping/facility management/geographic information system (AM/FM/GIS) systems. These systems are currently reducing the average outage restoration by over 30%, in comparison to utility control centers that do not have an integrated outage management system. OMS technology has progressed into determining \"where\" the actual outage has taken place. This has improved the dispatching of crews, provided the utility's customer service representatives with up-to-date outage knowledge and increased the effectiveness of outage restoration personnel. Overall reliability of the electric system has improved due to shorter outages and customer satisfaction is increased due to these shorter restorations.","PeriodicalId":328713,"journal":{"name":"ESMO '98 - 1998 IEEE 8th International Conference on Transmission and Distribution Construction, Operation and Live-Line Maintenance Proceedings ESMO '98 Proceedings.

Inc. or KEPCO has approximately 8000 km of power transmission lines and about 60% of these run over forested areas. Trees growing below the lines bring a risk of outage accidents even when they do not come into direct contact with such lines. In order to prevent these outage accidents, the Heliborne Separation Measuring System was developed jointly with the NEC Corporation. This system determines a 3D coordinate using a laser measuring unit mounted under a helicopter and calculates the separation between lines and trees. This advanced system has contributed to low cost and highly accurate performance in measuring.","PeriodicalId":328713,"journal":{"name":"ESMO '98 - 1998 IEEE 8th International Conference on Transmission and Distribution Construction, Operation and Live-Line Maintenance Proceedings ESMO '98 Proceedings.

This method enables a simpler, safer and more highly efficient means of installing line materials and heavy devices on utility poles which is a major job for overhead construction. Features of the developed robot system are the winch arm with a parallel link structure which provides easy access to heavy devices on poles, the efficient visual support system which provides easy access to the manipulator tool, and the new system frame which facilitates tightening bolts by means of semi-automation. The robot system on the boom is teleoperated by one man in the operation unit on the ground. Based on field test results, the authors found that the developed method increases the overall efficiency and level of safety while reducing workers fatigue.","PeriodicalId":328713,"journal":{"name":"ESMO '98 - 1998 IEEE 8th International Conference on Transmission and Distribution Construction, Operation and Live-Line Maintenance Proceedings ESMO '98 Proceedings.

Red Electrica has developed a new insulator washing system, based on a nacelle permanently suspended from the helicopter throughout the insulator high-pressure washing process. The nacelle is also secured to the line conductor, so that the nozzle can be aimed more accurately towards the insulator string and to maintain the high pressure water jet as long as is required to completely clean the insulator string. Under this system, the engine/pump assembly, tanks and spray nozzle are mounted on the nacelle, such that all the weight is suspended from the helicopter load hook. The nacelle design enables water reloading with both the nacelle and helicopter remaining airborne.","PeriodicalId":328713,"journal":{"name":"ESMO '98 - 1998 IEEE 8th International Conference on Transmission and Distribution Construction, Operation and Live-Line Maintenance Proceedings ESMO '98 Proceedings.
