Lodestar IDD /AUTOMATIC DISCONNECTOR / HIGH-VOLTAGE / OUTDOOR / OVERHEAD

タイトルまたは説明

Intelligent disconnector Lodestar IDD is designed for rapid remote sectioning of overhead power lines ***0 kV and for detection of stable and unstable fault processes including all types of phase-to-ground faults. Integration of  Lodestar IDD into power line automation system allows building an efficient and inexpensive line sectioning system.

Operational switching of sections of the electric circuit is performed by means of the automated drive located in the disconnectors control cabinet. The status of the disconnector is displayed on the dispatchers control panel and directly on the disconnectors control unit.

Lodestar IDD benefits:

• Selective detection of all types of emergency situation including phase-to-ground faults with low currents and unstable fault processes;
• Observability of each section of electrical grid through the use of fault indicators with the function of determination of fault currents direction;
• Automatic shutdown of a damaged section of the overhead line during the current-free pause of the reclosing;
• Fast power shutdown during transferring of information regarding a fault to a centralized system;
• Logical blocking of disconnectors control if there is voltage and / or current;
• Remote control of grid section;
• Integration to users SCADA system.
