Flexible AC Transmission Systems (FACTS) – What and why? FACTS is the acronym for “Flexible AC Transmission Systems” and refers to a group of resources used to overcome certain limitations in the static and dynamic transmission capacity of electrical networks. The IEEE defines FACTS as alternating current transmission systems incorporating power-electronics based and other static … Read more
What is a Strain Gauge A strain gauge is a resistor used to measure strain on an object. When an external force is applied on an object, due to which there is a deformation occurs in the shape of the object. This deformation in the shape is both compressive or tensile is called strain, and … Read more
Quantum numbers are like the addresses of electrons in an atom. They indicate the location, energy level, and spin of each electron, helping to define the electron configuration. There are four types of quantum numbers: Principal Quantum Number (n) The principal quantum number represents the main energy level, shell, or orbit an electron occupies. It … Read more
What is an Oscillator Transducer An oscillator transducer is a type of transducer that can be used to measure force, pressure, or displacement by converting it a voltage, which can then be measured by a voltmeter. Oscillator transducer are mostly used as secondary transducers, with their output calibrated in terms of their input quantity. Oscillatory … Read more
A digital frequency meter is defined as a general-purpose instrument that displays the frequency of a periodic electrical signal to an accuracy of three decimal places. It counts the number of events occurring during a set time interval. After each interval, the counter displays the value and then resets to zero. Different instruments operate at … Read more
What is a Signal Generator? Signal generators are electronic devices that produce electronic signals and waveforms. These signals can be repeating or non-repeating, depending on the application. Different types of signal generators have varying capabilities and functions. They come in different designs, sizes, and parameters to serve a wide range of purposes. Signal generators are … Read more
Steam power plants are crucial for power generation in the Asia Pacific. Improving their efficiency, even slightly, can save fuel and reduce greenhouse gas emissions significantly. It’s important to explore every possible way to increase the efficiency of the steam power cycle. The idea behind any improvement or modification is to increase the thermal efficiency … Read more
Sometimes, we need to switch on electrical loads using a computer program. For example, in a power plant, you might want to switch on a circuit breaker remotely. This can be done using a microcontroller. Let’s discuss how to make a Remote Control Circuit Breaker Using a Microcontroller. For this remote-controlled circuit breaker we will … Read more
In a control system, energy storing elements like inductors and capacitors are often present. These elements affect the system’s energy state, causing it to take time to transition from one state to another. This transition period is called the transient time, and the changes in voltages and currents during this time are known as the … Read more
Performance curves of a DC generator are graphs that show how the output voltage changes as the load current varies from no load to full load. These are also known as characteristic curves. These curves help us understand the voltage regulation of different types of DC generators. Better performance is indicated by lower voltage regulation. … Read more
