Safe grid separation for small hydroelectric power plants
- Applications:
- Hydropower Plants
- Renewable Energy
- Water & Waste
- Series/Measures
- Voltage
- Product:
- NA003
- Data sheet:
- en
- Task:
- When a small hydroelectric power plant is coupled to the public power grid, the power inverter must be equipped with a grid and system protection device that continually checks the grid quality and immediately decouples the system when a fault is detected. In this way, unintentional isolated operation is prevented, thereby avoiding a dangerous situation for maintenance personnel. Manufacturers of inverters require grid and system protection that fulfills the various standards of different countries with a single unit.
- Solution
- Grid and system protection from TELE safely separates small hydroelectric power plants from the grid in the event of a fault. The unit is programmable, making it suitable for all international standards.
- Use/value:
- - Ready for international use
- Freely programmable
- Flexible universal power supply
- Random thresholds and switching times for non-adjustable power generation possible
- Functional safety and detection of islanded operation
- Sealed and password protected
