Technical articles on Electronics and Electrical Engineering topics focused on Basics of EE, Electronic components, power systems and equipment used for generation, transmission, operation, and controls of electricity.
A thermal power plant is a power plant that converts thermal energy (heat) into electrical energy. In this post, Electrical Engineering XYZ shares basics of Thermal Power Plants. Basic Working of Thermal Power Plant A thermal power plant uses fuel to generate heat, which is then used to produce steam. The steam, in turn, drives … Read more
A special type of medium-voltage circuit breaker used to quickly interrupt and re-establish power in distribution lines is called a recloser. Download article here for reading later or continue reading below Reclosers are designed to trip if ever a distribution line suffers a “transient” (momentary) fault due to some natural event such as a lightning … Read more
Electrical Engineering XYZ shares article on Application of Line Reactors to AC and DC Motor Drives. Continue reading below or download PDF here for later reading. Regulating the electric power sent to an electric motor is a task performed by high-speed switching transistors inside a motor drive, modulating the pulse-width of a high-frequency square wave … Read more
Modern DC and AC motor drives provide features useful when using electric motors as final control elements. Some common features seen in both VSDs and VFDs are listed here: Not only are some of these limiting parameters useful in extending the life of the motor, but they may also help extend the operating life of … Read more
Plugging is the most powerful method of braking an electric motor, consisting of actively applying power to the motor in the opposite direction of its rotation. This is analogous to reversing the engine thrust of a power boat or an airplane in order to quickly bring it to a halt. For a VFD, this means … Read more
Rengerative braking is one of the braking methods used for AC Induction Motors Braking. In this article Electrical Engineering XYZ shares the fundamentals of DC Injection braking. Regenerative braking takes the concept of dynamic braking one step further, in converting the DC bus over-voltage into usable AC power to be placed back on the AC … Read more
Dynamic braking is one of the braking methods used for AC Induction Motors Braking. In this article Electrical Engineering XYZ shares the fundamentals of DC Injection braking. If a powered AC induction motor spins at a speed faster than its rotating magnetic field, it acts as a generator: supplying power back to the voltage source, … Read more
DC Injection braking is one of the braking methods used for AC Induction Motors Braking. In this article Electrical Engineering XYZ shares the fundamentals of DC Injection braking. If a spinning AC induction motor’s stator coils are energized with DC rather than AC, the rotor will find itself spinning inside a stationary magnetic field. This … Read more
