Energy Loss Of Transformers

Losses in Transformer As the electrical transformer is a static device, mechanical loss in transformer normally does not come into picture. We generally consider only electrical losses in transformer. Loss in any machine is broadly defined as difference between input power and output power. When inp

Impedance of Transformer

Leakage Reactance Definition In a transformer, not all the flux links both the primary and secondary windings. Some flux links with only one winding, called leakage flux. This leakage flux causes self-reactance in the affected winding. This self-reactance is also known as leakage reactance. When com

Eddy Current Theory and Applications

Eddy Current Definition According to Lenz’s law, when a conducting loop is exposed to a changing magnetic field, it generates an emf that induces a current opposing the change. Similarly, when a magnetic field changes through a conducting body, like a filament or a slab, it causes currents to flow t

Control Systems Block Diagram

Block Diagram Definition A block diagram is used to represent a control system in diagram form. In other words, the practical representation of a control system is its block diagram. Each element of the control system is represented with a block and the block is the symbolic representation of the tr

Transient and Steady State Response in a Control System

Transient Response of Control System As the name suggests transient response of control system means changing so, this occurs mainly after two conditions and these two conditions are written as follows- Condition one : Just after switching ‘on’ the system that means at the time of application of an

Signal Flow Graph of Control System

Signal Flow Graph Definition A signal flow graph simplifies control system diagrams by using nodes and branches instead of blocks and summing points. Rules for Drawing Signal Flow Graph The signal always travels along the branch towards the direction of indicated arrow in the branch. The output sign

Digital Data of Control System

Digital Data Definition Digital data in control systems consists of discrete or sampled data that represents continuous signals in a digital format. Sampling Process Sampling is the conversion of analog signals to digital signals using a sampler, which switches ON and OFF. The sampling process conve
