Television and Artificial Satellite (With Block Diagram) | Electronics

Throughout the history of human civilization, man has contrived in different ways to extend his sense of sight. The microscope, the telescope and the camera were important landmarks along the way. These inventions were based upon an important characteristic of the human eye known as 'persistence of vision'. Television is one of those miracles which enables us to view a [...]

Induction Type Directional Relays | Devices | Electrical Engineering

In this article we will discuss about induction type directional relays used in an electric circuit. Induction Type Directional Power Relay: The non-directional relay can operate for fault flow in either direction. In order to achieve operation for the fault flowing in a specific direction, it is necessary to add a directional element to the non-directional element. The directional (or [...]

Differential Relays and Its Types | Devices | Electrical Engineering

Differential protective relaying is the most positive in selectivity and in action. It operates on the principle of comparison between the phase angle and magnitudes of two or more-similar electrical quantities. Comparing two electrical quantities in a circuit by means of differential relays is simple in application and positive in action. For example, in comparison of the current entering a [...]

Impedance Relay: Operation and Types | Devices | Electrical Engineering

It is noteworthy here that in electrical engineering, the term 'impedance' can be applied to resistance alone or reactance alone, or a combination of the two. In protective relaying terminology, however, an impedance relay has a characteristic that is different from that of a relay responding to any component of impedance and therefore, the "impedance relay" is very specific. An [...]
