Machine efficiency

user

Machine efficiency refers to the ability of a machine or a system to convert input energy or resources into useful output with minimal waste or loss. It is an essential concept in various fields, including manufacturing, engineering, energy production, and technology.

Phase Rotation

user

Phase rotation, also known as phase sequence, refers to the order in which the voltage waveforms of a three-phase electrical system reach their peak values. In a three-phase system, there are three separate voltage waveforms that are 120 degrees out of phase with each other. The order in which these waveforms reach their maximum values determines the phase rotation of the system.

Leading and Lagging Reactive Energy

user

Reactive power is the power that flows back and forth between the electrical system and reactive elements such as inductors and capacitors. It is measured in volt-amperes reactive (VAR). When the reactive power leads the voltage waveform, it is called leading reactive power, and when it lags the voltage waveform, it is called lagging reactive power.

Maximum Demand

user

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

user

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.

Phase Angle

user

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.
