Electric power is now the mainstay of many technologies and applications. This is the term that is used to know the energy transferred by the electric circuit. Through the electric power industry, power will be supplied to households and businesses. There are multiple approaches to power generation and every application requires various levels of power. The generation of power is handled by the electric power industry. There might be the chances of getting … [Read more...]
What is a Permanent Magnet Synchronous Motor & Its Working
The creation of a synchronous motor took place in the year 1869 which was almost two decades back before the discovery of the induction motor. In the early stages of the 20th century, the development of induction motor happened, and its application was extensively developed. Whereas the reach of the synchronous motor was not more till the early period of the 1920s. Nearly, 5 years were needed to progress the necessary initial ability by interaction with … [Read more...]
What is Autotransformer Starter : Working & Its Uses
Initially, let us know what an autotransformer is, an autotransformer is the electric type of transformer that works only with one winding. The word “Auto” indicates that only one coil functions independently. Here, the sections that are present in the same winding operate as the transformer’s secondary and primary windings. Whereas, the general kind of transformer has individual secondary and primary windings. And then the invention of the autotransformer … [Read more...]
What is Centrifugal Switch : Functionality & Its Testing
In general, centrifugal switches are mainly used in single-phase and split-phase induction motors. The patent rights on this device were gained by Royal Lee during 1920. This stood as the foundation for the development of Lee Engineering Company. Before the development of centrifugal switches, the location of motors used to be inside the motor frame where it directed to the collection of a huge amount of grease, oil particles, dust which reduced the … [Read more...]
What is Rogowski Coil : Theory & Its Working
The evolution of the Rogowski coil happened with simple solenoids and these coils were in usage from the period 1912. The initial usage of the coil was very limited because of its minimal output voltage which was not enough to lead the measuring equipment. Whereas with the enhancement measurement sensitivity, the implementation of coil enhanced and those were in use in many applications across many domains. A tool that operates similar to the coil as … [Read more...]
What is Distance Relay : Theory & Its Characteristics
During the period 1809, a scientist named Samuel Thomas invented the first electrolytic relay which was a part of his electrochemical telegraph development. Later on, Joseph Henry, an American inventor asserted to have a relay invention in the year 1835 which was the improvised version of the electrical telegraph that was invented in 1831. But the relay which was currently in use today was designed by Samuel Morse in the year 1840. The mechanism of this … [Read more...]
What is Mutual Inductance : Derivation & Its Applications
In the domain of electronics and electromagnetism, inductance is the crucial concept where it is the inclination of a conductor to contradict the current flow. The current flow generates a magnetic field across the conductor. The field strength is based on the current’s magnitude and goes as per current changes. The word inductance was coined by Oliver Heaviside in the year 1886. In the name of Heinrich Lenz, the symbol of inductance was provided. The … [Read more...]
What is HRC Fuse : Construction & Its Working
Fuse is the most widely used terminology in the field of electronics and electrical engineering. This is the type of protective device which functions to safeguard electric circuits from high and over current ranges. These days, there exist numerous fuse designs where each type has its own features and characteristics based on the usage of the application. The history of fuse was initiated with the concept that Breguet suggested the implementation of … [Read more...]
What is Inductive Reactance : Derivation & Its Example
Once the equivalent values of DC & AC voltages are applied to the circuit which includes an inductor connected in series through the load. So the current supply in a DC circuit is more as compared to AC circuits due to the induced voltage that opposes the flow of current within the DC circuit once the flow of current reaches its highest value. When it approaches a fixed state value, then there is no more inductive effect. In AC circuits, the flow of … [Read more...]
What is an Isolation Amplifier : Features & Its Applications
An isolation amplifier is fundamentally used to reduce the common voltage between the source side and the power load side. They provide electrical isolation and acts as electrical safety barriers. They are also used to protect the operators from leakage currents. These are some of the most frequently used devices. They work fundamentally on the operational amplifier principle (OP-AMP). Due to their versatility, they find numerous applications in both … [Read more...]
