Satellite Communication | What is the role of Transponder in SC
As we know that satellites are the artificial moving devices which move around the earth with earth speed, means these satellites are synchronized with earth speed. So satellite communication means that powerful point to point communication system through which at we can communication around the globe at high speed. Basically, in satellite communication, the satellite…

Microwave & Microwave generation | How do they work?
Microwave Communication Microwaves mean high frequencies than 300 MHz and composed of short wavelength less than 1m waves. So those electromagnetic waves which have high frequencies but having short wavelength are called microwaves. The communication which is done through microwaves is called microwave communication. In other words, the communication in which the microwaves are used as…

Introduction to Timers | Multi-vibrators | Types of Multi-Vibrators
Timers or Multi-vibrators Today we are going to discuss the digital electronics application called timers or multi-vibrators “Timers are those circuits which provide specific periodic signals to the digital circuits. These signals are capable of changing the condition of those systems” it can be defined as that “multi-vibrators are those circuits which provide those signals…

Hydroelectric Power Station: Site selection | Key Components | How it works?
What is Hydroelectric Power Station & How it Works? As we know that hydro means water, So the generating station where the water potential energy is utilized at a high level for the generation of electrical power is known as a hydroelectric power station. Hydro-electric power stations are usually built on the hilly location where…

Role of Buchholz relay in transformer Protection system | 2018
What is Transformer Protection System? In common practice, there are so many protection systems being used for the protection of alternator, but power transformers are also an important machine which is to be protected from abnormal conditions. A Merz-price circulating current system is undoubtedly the most satisfactory protective system from alternators. Now we need a…
