The system is 6x361 kW Forced Cooled Dynamic Brake System and consists of Six Nos. of Grid Resistors mounted on the Short Hood structure and a complete Blower Motor Assembly.
Advantages of this system is: -Better Insulation Resistance (IR) value due to better insulating material used i.e. Thermoset Moulding material in comparison to old DBR in which Asbestos cement board is used as an insulating material.
Low temperature rise of 300 - 375°C resulting in longer life of DBR.
Better Cooling due to smooth intake of Air.
