Maximum Demand

Electricity tariffs are rising hence understanding your energy bill is the first step to control your energy use and reduce costs. There is often a figure shown as ‘Maximum demand’. What does it mean and why should you be interested?

Swell Voltage

Electricity is an integral part of our lives, and we rely on it for everything from lighting our homes to powering our devices. However, there are times when the voltage levels in the electrical system can fluctuate, which can have significant impacts on our equipment and appliances. Two such voltage fluctuations are swell and sag voltage, which we will explore in this blog.

Crest Factor

Crest factor is a term used to describe the ratio of the peak value of an electrical waveform to its effective value, which is also known as the root mean square (RMS) value. It is a measure of the shape of an electrical waveform and is used in many areas of electrical engineering and electronics. In this blog, we will explore what crest factor is, how it is calculated, and its significance in electrical systems.

Phase Angle

Phase angle refers to the angular difference in degrees or radians between two alternating electrical quantities. It is commonly used to describe the relationship between voltage and current in AC circuits. In a sinusoidal AC circuit, the voltage and current waveform are typically out of phase with each other.

Reactive Energy

Reactive energy, also known as reactive power, is a type of electrical energy that oscillates back and forth between electrical equipment and the power grid. Unlike active power, which is the energy that is actually consumed by electrical devices to perform work, reactive power does not produce any useful work on its own. Instead, it is required to maintain the voltage levels of the power grid within acceptable limits.

Harmonic Current

Harmonic current refers to the electrical current that flows through a system at a frequency that is a multiple of the fundamental frequency. These harmonic frequencies can cause problems in electrical systems, as they can create additional heat, noise, and electromagnetic interference, which can damage equipment and reduce system efficiency.

Harmonic Voltage

What is Harmonic in Electrical? Harmonics are electrical signals that occur at frequencies that are multiples of the fundamental frequency of a power supply. Harmonic distortion occurs when non-linear loads draw non-sinusoidal current from the power supply. This results in a voltage waveform that is distorted and contains harmonics. Harmonics can cause problems such as […]
