BRAKING RESISTOR

Unlike a heater where electric current passes through resistive wire to generate heat for specific purposes such as heating a medium, a Braking Resistor works the reverse way and is used in electrical drive system.

When a machinery is required to stop, the action of decelerating of the motion transforms kinetic energy into electrical energy and this process is known as dynamic braking which can be either regenerative braking or rheostatic braking.

In regenerative braking, the electrical power generated is put back into power system whereas in rheostatic braking, it is being dumped through the resistor which acts as a load bank and dissipated as heat.

WHAT WE OFFER

DFINITI customizes design and builds Braking Resistor in a wide range of duty and can be water-cooled or air-cooled, arranged in single or multiple bank unit to suit different needs.

APPLICATION

Braking Resistors are commonly used in various types of industries and they play a part in different applications specifically for Marine and Offshore industry which include:

  • Drilling Rigs
  • Ships
  • Barge and offshore support vessel
