An asynchronous motor is a most extensively used motor in the industry, It is almost impossible to think of an industry without using this motor, due to its operation at the sub-synchronous speed it is known as an asynchronous motor. Having assumed such an important role it becomes imperative to study it in detail. This article discusses an overview of the asynchronous motor like its definition, working, construction, differences, and applications. What … [Read more...]
What are Welding Joints : Types and Their Benefits
These days, metal fabrication is the most popular metal soldering technique, implemented in many industries, but these fabrication techniques are not achieved without welding. So, welding has been around with us from the ancient period itself. The ancient period of welding involves the hammering of two metal pieces under heat until they are connected. The initial and modern welding method was invented by Sir Humphry Davy where an electric arc is generated … [Read more...]
What is Breakdown Voltage : Avalanche Breakdown & Zener Breakdown
When we are about to discuss the concept of breakdown voltage, first we need to think about the concept of why it is needed and why it has to be implemented? So, let’s go with a clear interpretation. For the functioning of power transmission systems, there will be a requirement of power transformers. The insulation medium in the transformers gets reduced when it is made in contact with moisture, acids, oxygen, and heat. Of all these, heat is the foremost … [Read more...]
What is Electrical Conductivity : Working Principle, Formula & Applications
The history of electrical conductance invention takes back to the eighteen and nineteen centuries where Mr. Benjamin Franklin (1706–1790) observed that electrons could travel along the path of the metallic rod; which also resulted in the invention of a lightning rod. Mr. Alessandro Volta (1745-1827) studies on static electricity have led to the discovery of electric potential and the principle behind the development of batteries. Mr. Georg Simon Ohm … [Read more...]
What is Piezoelectric Transducer : Theory, Circuit, Formula & Applications
We all might come across the situations of energy conversions either in our day-to-day life scenarios or in industrial purposes. So, for the conversion of energy, we need a device to calculate the unfamiliar quantities and calibrations. And the device that comes into invention is “Transducer”. As every scenario that we come across either directly or indirectly related to the energy conversion, there are many kinds of transducers and their application is … [Read more...]
What is Dielectric Heating : Circuit Diagram and Its Working
We all know that the progression of technology enhances day-by-day through the invention of various trends and creativities. In the same way, the approaches to cooking food and making use of fire also get enhanced. We are completely aware of how to cook, molding of metals and procedures followed in various industries and many others. But the greatest revolution that came into existence was to work on the same thing without the utilization of fire. The … [Read more...]
What is Earthing : Components and Its Types
We know that all the electrical and electronic appliances run on electricity. The home appliances are like air conditioners, refrigerators, televisions, greasers, washing machines, grinders, etc. Have you ever noticed that why the plug systems on the wall contain three pins instead of two pins? Home appliances are designed with metals, metal components, and metal frames. Metals are great conductors that allow the flow of current through it. But there is a … [Read more...]
Induction Heating Working & Its Applications
The fundamental induction heating principle was introduced and applied in manufacturing industries in 1920. During the Second World War, the development of technology has been increased to reach urgent requirements of a period of war for a quick, consistent procedure to solidify the parts of the metal engines. At present, technology is focusing on lean industrialized methods & giving importance to improved quality control of induction technology. This … [Read more...]
Maximum Power Transfer Theorem – Examples and Applications
In any electrical system, the highest amount of power is used to transmit the power to the load for its operation. the best example of this is an audio amplifier as they transmit the maximum amount of current from the amplifier to the speaker. Similarly, in radio system, the highest amount of current is supplied from the power amplifier to the antenna. For this, the value of load resistance should be ideal for supplying the highest amount of current toward … [Read more...]
Overvoltage and Under Voltage Protection System
If any unexpected fluctuation in the power supply may cause many problems in the industries, homes, offices. Voltage fluctuations in the electric power supply have a very poor effect on connected load. These fluctuations of over voltage and under voltage protection system are produced by many reasons which are like voltage surges, limiting, overload and etc. General applications of these systems are used in agriculture motors, water pumps and etc. In this … [Read more...]
