A Look at Power Resistors

Many power run applications and industrial systems produce and use a lot of power which when not carefully handled may lead to loss and damage of property including electrical applications. To manage this, many users invest in power resistors. Power resistors are used to dissipate large amounts of power either through conversion or loss as heat.There are various types of power resistors namely dynamic braking resistors, grounding resistors and load bank. They all perform assorted functions depending on their specifications. Find out more on wirewound resistors

Grounding resistors, also known as earthing resistors are used to ground power systems, increase resistance and limit currents for the safety and reliable protection of equipment and workers in industrial plants. Load banks are power resistors that develop electrical loads containing components used to absorb heating elements from running electronic applications such as generators, power sources and batteries. Thirdly, there are dynamic breaking resistors. These resistors are used to transform kinetic energy to electrical energy. These resistors convert kinetic energy to electrical energy. This process is known as dynamic braking and it is mostly used to slow down mechanical systems. Dynamic braking is further broken down to rheostat and regenerative. In rheostat braking, the energy produced is diffused through a resistor while in regenerative braking, the electrical power that is produced is fed back into the mechanical systems. Also see high power resistors

Other types of resistors such as current sense resistors and current shunt resistors exist in circuits. In context, the word shunt, in connection to the resistors mean that the resistors work parallel with the ammeters in circuits by diverting currents. Many shunt resistors are developed using metallic components to ensure their compatibility with a range of applications such as automotive, portable devices and industrial systems that require a high degree of effectiveness. Power resistors are further divided into two categories namely low power resistors and high-power resistors. Applications use either of the two depending on their specifications, capabilities and levels of power production. The measure of the low power resistor and high-power resistors are below an eighth of a watt and over a watt, respectively. Power resistors are often larger in size than other power applications due to the amount of heat they need to dissipate. The bigger the size of the power resistor, the more the heat lost when using the resistor. However, researchers are looking into inventing resistors that are smaller in size but can still function effectively. In closing, power resistors play an important role in electronic application and industries by ensuring surge protection, protection of personnel and appliances.
