Disadvantages of DC Generators
- A significant disadvantage of a DC generator is that it cannot be utilized with a transformer.
- DC generators have low efficiency.
- The current flowing in the generator undergoes numerous losses such as Eddy current losses, copper losses, mechanical losses, among others.
- DC generators installed over a long distance may face significant voltage dips.
Construction And Working of a DC Generator
In 1831, Michael Faraday, a British physicist, devised the electromagnetic generator. The primary function of this device is to convert mechanical energy to electrical energy. There are several types of mechanical energy sources available, including hand cranks, internal combustion engines, water turbines, and gas and steam turbines. The generator provides capacity for all electrical power networks. An electric motor should be able to perform the generator’s converse function. The basic purpose of the motor is to convert electrical energy into mechanical energy. Generators and motors have many properties.
