HIGH ENERGY DUMP LOAD RESISTORS /
FAULT RIDE THROUGH RESISTORS
Resistors for high Energy Consumption from Wind Turbines during short grid loss situations.
If the power mains voltage has short breaksdowns as shown on the upper curve a modern wind generator has to continue producing energy for a specific time i.e. 2 - 5 seconds making it possible for the wind generator to support the grid during re-establishing of mains voltage. The CBT resistors made for this purpose has extreme capacity of consuming energy. A CBT 500 mm can consume 1M J during 2 – 5 seconds and a resistor bank of i. e. 4 CBT 500 resistors can absorbe 4 MJ.
The tempersture on the surface will only be influenced with a rise of temperature less than
POWER FILTER RESISTORS
To remove harmonics from converter generated AC Voltage Danotherm supplies resistors for Power Filters in Wind Turbines.
Filter resistors for PWM and dV/dT filters belonging to the APLPHA Range or Wirewound Ceramic resistors.
