Most of the relays used in the power system operate by virtue of the current and/or voltage supplied by current and voltage transformers connected in various combinations to the system …
What is a Static Relay? There are two basic classifications of relays – Electromechanical Relays and Solid State Relays (Static relay). One main difference between them is electromechanical relays have …
The ratio of output in kWh to the input in kWh of a transformer over a 24-hour period is known as all day efficiency. The ordinary or commercial efficiency of …
Primary and Back-up Protection Primary protection (Main protection) is the essential protection provided for protecting an equivalent/machine or a part of the power system. As a precautionary measure, addition protection …
What is Load Forecasting? Electrical energy cannot currently be stored in large amounts. It has to be generated whenever there is a demand for it. It is, therefore, imperative for …
We have already discussed the working of electrical relays. Now we are going through different types of electrical relays. There are two basic classifications of relays: Electromechanical Relays Solid State …
In this article, we are going to study the basics of low voltage circuit breaker design and construction. The operation and arc extinction of different types of circuit breakers were …
The difference in level between points of supports and the lowest point on the conductor is called sag in overhead transmission lines. Sag in Hot and Cold Day While erecting …
What is Corona? The phenomenon of violet glow, hissing noise and production of ozone gas in an overhead transmission line is known as the corona. In this article, we will study …
