The armature will draw a very high current due to the small resistance of the armature winding to avoid this heavy starting current 4 Point starter is used. Here we are going to discuss the 4-point starter it’s working principle and…
The three-phase induction motor is one of the most widely used motors in various industrial applications. Its robust construction, simplicity, and versatile nature make it a preferred choice for powering machinery and equipment. In this article, we will delve into…
Mainly two tests are carried out on the electrical transformer which are the open circuit test and short circuit test of the transformer also known as the SC and OC tests. Key takeaways: The purpose of these tests is to…
What is harmonics in power system? A power system harmonic is defined as a component of a periodic wave having a frequency that is an integral multiple of the fundamental power line frequency of 60 Hz. distortion in electrical current and…
Electrical Insulators are used in an overhead line to provide insulation to power conductor from ground and tower or supporting structure. Generally, insulators are connected to cross arm of supporting structure and power conductor pass through the clamp of the insulator. In this…
A machine that converts DC power into mechanical power is known as DC motor. Dc motor has different types, dc motor has been used in industrial applications for years. Connecting with DC drive, dc motor provides very accurate control over…
Armoured cables represent a significant advancement in the field of electrical engineering, designed to offer enhanced safety and protection in demanding industries and environments. Comprising various elements such as conductors, insulation, bedding, armour, and sheath, these power transmission linchpins are…
What is the power factor and power triangle? In the modern electrical distribution system, most of the loads are inductive in nature like motor,transformer, electrical furnace. when induction motor run on no load or light load, create lagging power…
Advantages of Direct current transmission compare to AC transmission Why we use HVDC transmission instead ac transmission? 1) HVDC Transmission can operate with one conductor and ground as return path.on other hand AC transmission required 2 or more conductor, Hence…
1 phase induction motors are widely used in many applications due to their simplicity, cost-effectiveness, and simple operation. They are commonly used where a three-phase power supply is not available or practical. In this article, we will explore the construction,…
