Determining the efficiency of a DC machine is an important part of electrical engineering. While direct loading tests provide accurate results, they require large amounts of power and heavy loading equipment. To overcome these challenges, engineers often use indirect testing methods.
One of the most widely used methods is the Swinburne test. It allows engineers and students to estimate...
Electrical measurements often involve determining current, voltage, or resistance. However, in many laboratory experiments, engineers and physicists need to measure the total quantity of electric charge that flows through a circuit in a very short time. This is where a ballistic galvanometer becomes useful.
A ballistic galvanometer is a specialized measuring instrument designed to detect...
The ability to control the speed of electric motors has always been critical in industrial applications. Before the development of modern electronic drives and variable frequency drives (VFDs), engineers relied on several mechanical and electrical methods to regulate motor speed. One of the most effective and widely used techniques was the Ward Leonard method of speed control.
The Ward Leonard...
TL;DR The two wattmeter method is a practical, mathematically proven technique for measuring total power in a 3-phase, 3-wire system using only two instruments. This blog explains the science behind it, how Blondel's Theorem justifies it, how wattmeter readings are interpreted, and why it remains the go-to method in industrial electrical engineering.
For electrical engineering...
A DC regulated power supply is an essential electronic device used to provide a stable and constant DC voltage output regardless of changes in input voltage or load conditions. It is widely used in electronics laboratories, engineering experiments, testing environments, and industrial applications where accurate and reliable power is required.
Understanding how a DC regulated power supply works...
An AC series motor is a type of electric motor that can operate on alternating current (AC) supply while maintaining characteristics similar to a DC series motor. Because of its high starting torque and compact design, it is widely used in household appliances and power tools.
If you are an electrical engineering student, technician, or someone interested in motor technology,...
In physics and engineering laboratories, precision measurement is critical. One such highly accurate instrument used for linear and angular measurements is the travelling microscope. If you’ve ever wondered what a travelling microscope is and how professionals take accurate travelling microscope reading, this guide explains everything in simple terms.
Whether you are a student, lab...
When buying a test and measurement instrument, oscilloscope price is often the first factor engineers, students, and labs look at. Digital oscilloscopes are available across a wide range of budgets, from affordable entry-level units to high-end professional systems. But what exactly do you get at each digital oscilloscope price point, and how do you know which one is right for your...
In today’s automation-driven world, industries rely heavily on smart control systems, advanced machinery, and digitalized processes. To build the skills required for such environments, educational institutions and training centers need practical learning tools that combine real industrial components with interactive experiments. A PLC Training Platform serves exactly this purpose by...
