In electrical substations, an interconnected system of multiple capacitors is used for improving the power factor of the system, this interconnected system of capacitors is referred to as a capacitor bank. In short, a capacitor bank is device which consists of multiple capacitors connected in parallel or series and provide reactive power for improving the power factor of the electrical system. Capacitor banks are important components in utility and industrial substations as they are useful in improving power factor and efficiency of the power supply system. Read this article to learn the basic concepts related to a capacitor bank, ... Read More
In electrical engineering, CVT stands for Capacitive Voltage Transformer. It is a specially designed electrical transformer used for stepping down the high voltage of incoming supply to a low voltage for metering, protection and automation. It is an important component of an electrical substation. Sometimes, CVT is also referred to as CPT (Capacitive Potential Transformer). In this article, we will learn about CVT, its function, advantages, and applications in electrical power systems. So, let’s start with the basic definition of CVT. What is a CVT Transformer? CVT or Capacitive Voltage Transformer is an instrument transformer used in electrical systems, mostly ... Read More
In electrical power systems, different types of switchgear devices are used such as circuit breakers, AB switches, isolators for switching and protection purposes. These switching devices play an important role in power systems. There are two common types of switch devices used in electrical power systems are AB Switch (Air Break Switch) and Isolator. Although, the primary purpose of both AB switch and isolator is similar, but they are completely from each other in construction, operation, and many other aspects. For an electrical engineer, it is very essential to understand the differences between AB switch and isolators to design ... Read More
An electrical transformer is one of the most widely used electrical machines in power system. The main function of a transformer is to change the voltage levels in the system for different purposes. Depending on the purpose, these transformers can be classified into different types like step-up transformer, step-down transformer, or isolation transformer. The step-up or step-down transformers can also be referred to as regular transformers. These are used for changing the level of supply voltage. On the other hand, an isolation transformer is used for providing an electrical separation between the input and output circuits. The most fundamental ... Read More
In electrical engineering, there are several different types of transformers for different applications. Two such transformers are CVT and PT.CVT stands for Capacitive Voltage Transformer and PT stands for Potential Transformer. Both CVT and PT are the types of instrument transformers and thus are used in protection and metering applications. However, they are different from each other in many aspects. The primary difference between CVT and PT is that a CVT (Capacitive Voltage Transformer) utilizes a capacitor voltage divider and a step-down transformer to convert a high voltage into a low voltage, while a PT (Potential Transformer) utilizes only a ...

Residual Current Circuit Breaker (RCCB) is a type of circuit breaker used in electrical circuits for protection purposes. The primary function of an RCCB is to detect a leakage in the circuit current. If there is any leakage in the current, the RCCB can interrupt the circuit and prevent the fault to be happened. Read this article to understand the functions, working principle, advantages, and applications of RCCB. What is an RCCB? RCCB (Residual Current Circuit Breaker) is a protecting device that detects any leakage current in the circuit and interrupt the circuit current. When a fault occurs in ... Read More
ArrayList to ArrayList Instead of the typed parameter in generics (T) you can also use “?”, representing an unknown type. These are known as wild cards you can use a wild card as − Type of parameter or, a Field or, a Local field. Using wild cards, you can convert ArrayList to ArrayList as − ArrayList stringList = (ArrayList)(ArrayList)(list); Example import java.util.ArrayList; import java.util.Iterator; import java.util.ListIterator; public class ArrayListExample { public static void main(String args[]) { //Instantiating an ArrayList object ...

Python has built in file creation, writing, and reading capabilities. In Python, there are two sorts of files that can be handled: text files and binary files (written in binary language, 0s, and 1s). While you can create files you may delete them when you no longer need them. It is simple to create directories programmatically, but you must ensure that they do not already exist. You'll have difficulties if you don't. Example 1 In Python, use the os.path.exists() method to see if a directory already exists, and then use the os.makedirs() method to create it. The built in Python ... Read More
To find the third largest number of the given array, first of all, sort the array.Sorting an arrayCompare the first two elements of the arrayIf the first element is greater than the second swap them.Then, compare 2nd and 3rd elements if the second element is greater than the 3rd swap them.Repeat this till the end of the array.After sorting an array print the third element from the end of the array.ExampleLive Demopublic class ThirdLargestNumberInAnArray { public static void main(String args[]){ int temp, size; int array[] = {10, 20, 25, 63, 96, 57}; size = array.length; for(int i = 0; i
