Development and qualification of a temporary supporting device for HV electrical substations

摘要

The transmission network development along with the connection of new customers and compensating systems call for extension works in existing substations. In order to address that growing need while minimising down time, Rte has acquired new Temporary Supporting Devices for High Voltage Electrical Substations. Such devices make it possible, per example, to carry out works on busbars keeping uninterrupted service on Rte network. SERECT was asked to design the new device, which was developed in about two years. It meets applicable French, European and LW regulations.
