Web admin Introduction A hipot test is shirt for “high potential” or “high voltage” test or dielectric strength testing, is a type of electrical test which is performed to assess the electrical insulation of a device or component. This is used to ensure the safety and reliability of electrical equipment. Purpose of this test is to check … Read more
Basic Principle of step down transformer A transformer whether its Step down transformer or Step up transformer ,they work on the same basic principle which is called Electromagnetic Induction. A transformer is an electrical device that transfers electrical energy from one circuit to another through mutual electromagnetic induction. What is Electromagnetic Induction? This phenomenon was … Read more
Distance Protection relay is a key component of electrical protection systems. It acts as a guardian, ensuring the power grid remains functional even in adverse conditions. Distance relay specifically focuses on the impedance of a transmission line and it is directional in nature. It plays a pivotal role in protecting power lines from faults, such … Read more
What do we understand by Power flow analysis? Power or load flow analysis helps in understanding how electrical power is distributed and balanced throughout the network.The primary objective of power flow analysis is to calculate the steady-state voltages, currents, and power flows in an electrical network under different operating conditions. It helps ensure that the … Read more
What is power factor? The power factor is a measure of how effectively electrical power is being converted into useful work output within an electrical system. It’s a dimensionless number between 0 and 1. A power factor of 1 means all the electrical power is being used for productive work, while a lower power factor … Read more
Introduction Electric drawing of metering circuit in a control panel refers to the electrical circuitry and components designed to measure various electrical parameters within a system or equipment. This circuit plays a crucial role in monitoring and managing the electrical characteristics of the system. Here are some key points to understand about a metering circuit … Read more
Electrical drawing of Tripping circuit implies the wiring diagram which is designed in a way that it will trip the circuit breaker either on some fault or manually through trip and close switch (TNC Switch). Different relays are used for protection and they are housed in control and relay panel and purpose of these relays … Read more
What is Impedance matching? It is the balance between the source and load impedance to ensure the load receives maximized power and it is very necessary for optimal flow of power between two interconnected devices. We know that Impedance combines both resistance (R) and reactance (X) and it is expressed as a complex number: Z … Read more
Electrical insulators are materials or devices designed to block the flow of electric current. They serve as barriers, preventing the conduction of electricity between conductive materials. This is achieved through their unique property of high electrical resistance. Types of Electrical Insulators No.of discs required for different voltage level can be calculated using the formula given … Read more
Introduction Sepsis is a very serious ,life threatening medical condition which requires special attention and treatment by health professionals. Sepsis is body extreme response to an infection. In most cases , sepsis may start before a patient goes to the hospital. Bacterial Infections that lead to sepsis most often start in the lung, urinary tract, skin, … Read more
