What Are the Best Earth Fault Repair Methods?
An earth fault is where an unwanted electrical contact is established between a current-carrying conductor and an earthed object, for example, the metal structure of the system or the earth. Earth faults are usually the result of installation mistakes, weather, wear and tear on...

How can power quality problems be detected?
Power quality is a critical aspect of electrical systems, directly impacting the efficiency, reliability, and cost-effectiveness of operations. Power factor (PF) is that of actual power, in kilowatts, kW, relative to apparent power, in kilovolt-amperes, kVA. This is a measurement of how effectively electrical...

Harmonics – What are some of the ways to detect them?
The presence of harmonics in electrical systems has been an issue in power quality and efficiency. These are the voltage or current waveforms, which appear at frequencies that are integer multiples of the fundamental frequency. For example, if one considers Australia’s power grid as...

Power quality meter – What is the purpose?
A power quality meter is designed to capture measurements and analyses of the critical parameters that determine the quality of electrical power for a system. The major critical parameters involve voltage, current, frequency, harmonics, and waveform distortions. It is with power quality meters that...

How to calculate prospective short-circuit current
To calculate prospective short-circuit current, this usually implies the maximum fault current that would possibly occur at a point in an electrical system, one must consider factors such as the system voltage, the impedance of the system, and the type of fault. Here’s how...

Voltage drop and voltage rise – The differences
The term used for the loss of electrical energy in the flow through a conductor or electrical device is referred to as voltage drop. The conductor or device has a resistance and will therefore retard the flow of such electric charges, which results in...
