Are you looking for information about static relay and its advantages, then there is nothing to worry because today our topic is about it. So first of all we will know its definition and then we will know its benefits. So let’s start. Static relay definition A relay that does not have any moving parts … Read more
Here we are going to discuss about the protective relays. So first of all we will know the what is relay and then gradually we discuss relays all important parts. So stay with us till the end. What is relay ? A protective relay is a device that detects the fault and initiates operation of … Read more
Today in this article we will get some information from fault in Power System. So let’s see what we will get to know from this article. What is a fault in power system? A fault indicates abnormal conditions in the circuit. Most faults in a power system cause a short-circuit condition. because when such a … Read more
A Wattmeter, as its name implies, measures the electrical power given to or developed by an electrical device or circuit. A wattmeter is rarely needed in D. C. circuits because the power (P = VI) can be easily determined from the voltmeter and ammeter readings. However, in A. C. circuits, such a calculation is generally … Read more
If you want to measure anything, then a kind of instrument is needed for that. So let’s know about some tools or instruments for measurements. So let’s start. What are the instruments for measurements? Some instruments use for measurements in electrical engineering include a galvanometer, an ammeter, a voltmeter, electrodynamic, a moving iron and a … Read more
Today you are going to get some information, that is short circuit in electrical. So first we will see the definition then after that we will see what is the causes of short circuit, what is its effect and then what is short circuit current in electrical. Stay with us to get the answer of … Read more
Here today we are going to study different types of bus bar arrangements. The aim of any particular arrangement of bus-bar is to achieve adequate operating flexibility, sufficient reliability and minimum cost. When connecting multiple generators or feeders operating at the same voltage directly electrically, a bus-bar is use as a common electrical component. Bus-bars … Read more
Definition switchgear – The equipment used for switching, controlling and protecting electrical circuits and devices is known as switchgear. Switchgear equipment essentially consult with switching and interrupting current under normal or abnormal operating condition. What are the essential features of switchgear There are five types of essential features of switchgear as you can see below … Read more
We discussed about R – triggering and RC – triggering in the previous article. So today we are going to discuss about UJT relaxation oscillator. UJT means Uni Junction Transistor and it is commonly use to trigger SCR. It is a 3-terminal, 2-layer and one PN junction diode. UJT junction ( Uni junction … Read more
As we know there are three types of firing circuits. And we read in the previous article Resistance triggering circuit. So today we are going to study RC Triggering circuit of SCR. There are two types of RC Triggering circuit. So first we will read RC half wave triggering circuit and then RC full wave … Read more
