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 ...

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

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 an electrical system, there are three types of conductors used, they are phase, neutral, and ground. In general, the neutral wire is grounded for safety and stability reasons. But sometimes, a condition occurs where the neutral wire of the systems is disconnected from the ground terminal, this condition is known as floating neutral. In some special situations, the neutral wire is intentionally left isolated from the ground terminal, this is also known as floating neutral. In this article, we will learn about floating neutral in electrical systems, its effects, causes, and methods of testing and fixing the floating ... Read More

In electrical power system, there is a device called Automatic Voltage Regulator (AVR) used to adjust the voltage levels within a desired limit. In other words, an automatic voltage regulator is an electronic circuit that is primarily used for regulating the output voltage of an electric generator, so that we can obtain a constant voltage even when the load is fluctuating. This tutorial will explain the construction, working, needs, advantages, and applications of automatic voltage regulators (AVRs). So, let’s start with the basic introduction of automatic voltage regulator. What is an Automatic Voltage Regulator? An AVR or Automatic Voltage Regulator ... Read More

In electrical machines, an induction motor is a type of alternating current (AC) motor which operates on the principle of electromagnetic induction. Induction motors are classified into two types depending on the power supply used; they are single-phase induction motors and three-phase induction motors. In this article, we will primarily focus on studying about three-phase induction motors and their faults. One of the important points about three-phase induction motors is that they are very commonly used in a wide range of domestic, commercial, and industrial applications due their smaller size, low cost, and higher efficiency. Before going to discuss ... Read More

An alternator is an electromechanical energy conversion device that converts mechanical energy into alternating current electrical energy. An alternator is basically a synchronous generator that produces electricity at a certain frequency. To drive the alternator, a prime mover is used. Some commonly used prime movers are steam turbine, water turbine, gas turbine, and diesel engine. Like any other rotating electrical machine, different types of faults can also occur in an alternator. Due to these faults, we get a reduced efficiency and performance of the alternator. Further, these faults can cause malfunctioning or complete failure of the alternator that imposes ... Read More

An inverter battery is an electrochemical device that is used for storing electrical energy. It is a type of rechargeable battery that works with an inverter to provide continuous power supply in the case of main supply outages. An inverter battery charges when main power supply is available and it delivers the stored electrical power when the main power supply is disrupted. In this article, we will explain the different types of inverter batteries along with their advantages and disadvantages. But before that let us get an overview of inverter batteries and know about their specifications. What is ... Read More

In today’s world of automation, electric motors play a vital role in all industries and businesses from automobiles to robotics and home appliances. Electric motors are used to convert electrical energy into mechanical energy to drive different kinds of loads. With technological advancements, different types of electric motors have been developed which are having different characteristics to match the requirements of different applications. However, the basic construction of all electric motors is the same, having two main components namely, stator and rotor. Where, the stator is a stationary part and the rotor is the moving part of the motor. Since, different ... Read More
