In the bronze age itself, the concept of welding was in implementation. An example of this is the making of gold boxes with the assistance of pressure welding. At the time of middle ages, the concept of blacksmithing was formed to weld iron pieces. Every consecutive year, there comes the evolution of a new type of welding and plasma arc welding is the one. This process was discovered by Robert M.Gage in the year 1953. The unique feature that made this … [Read more...]
What is Distribution Transformer : Construction, Types & Its Uses
The men behind the invention of the transformer are William Stanley, Lucien Gaulard and Sebastian and employed the device for both commercial and practical applications. Then, the modern type of transformer was invented in the year 1886 where this used AC power as the power source. Ranging from radio systems to microelectronics, these transformers are extensively utilized from the time of their invention. The presentation of the distribution transformer … [Read more...]
What is Three Phase Transformer : Circuit Diagram and Its Working
In this industrial era, the transformer stood as a crucial invention as it serves the requirements and necessities of multiple industries. The essence of the transformer lies completely in its energy conversion. Based on the principle of electromagnetic induction, Faraday expanded this concept to a transformer and even this device almost functions on the same principle. So, the primary kind of transformer that was invented in the induction coil. Whereas, … [Read more...]
What is Transformer Testing : Types and Working
The transformer, as the name suggests is for transforming power from higher voltage to a lower voltage and vice-versa. In electrical engineering voltage for different functions/purposes is different; Therefore, the Transformer assumes a most important role. The importance of a transformer (distribution) is such, that it affects the general public directly as without electricity nothing moves. In order to perform, a transformer has to be tested thoroughly … [Read more...]
What is Star Delta Starter : Circuit Diagram and Its Working
The starting of an induction motor is associated with high inrush current (magnetizing and load). This inrush of current which maybe four to five times the full load current(FLC) of the motor poses problems in the supply system and the motor itself. In order to restrict the inrush of current suitable voltage reducing starting device is to be used. Star Delta starter being one such device. It may be added that with the improvement in the supply system and … [Read more...]
What is a Piezoelectric Effect : Materials and Its Applications
We may use many materials like cane sugar, quartz, Rochelle salt, and others without knowing what exactly they are and their benefits. But today, this article explains you clearly on these materials because these are piezoelectric materials and they are evolved with piezoelectric effect. This effect was first observed by Jacques Curie and Pierre in the year 1880. With the knowledge they have on the concept of pyroelectricity and crystal structures and … [Read more...]
What are Piezoelectric Material : Types and Their Properties
For the initial experimentations on piezoelectricity, the materials that were used were crystals and introduced the concept piezoelectric effect in the year 1880. With the investigations done on few materials, the two materials those exhibited maximum piezoelectric effect were Rochelle salt and Quartz. In continuity with the investigation done on a piezoelectric material, they exhibited good properties, characteristics, and benefits. And the initial … [Read more...]
What is Zener Diode : Circuit, Working Principle & Characteristics
In the developmental era of semiconductor diodes itself, Zener diodes were founded. Every electronic circuit is basically composed of diodes. So, diodes hold utmost prominence in the development of electrical and electronic devices. The characteristics of Zener diode were initially described by Clarence Melvin Zener in the year 1934. From then, there has been enormous progress in the implementation of these devices. To know about Zener diodes, one has to … [Read more...]
