Estimating maximum demand is a topic frequently discussed. Working out how much power to allow for a building can be very subjective . Allowing too much...
Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...
Photovoltaic (PV) cells (sometimes called solar cells) convert solar energy into electrical energy. Every year more and more PV systems are installed...
When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
Electrical engineering has a multitude of laws and theorems. It is fair to say the Ohm's Law is one of the more widely known; it not the most known. Developed...
Problems on achieving maximum voltage drop within an installation come up often. Depending where you live, local regulations will have different limits...
American inventor Thomas Alva Edison was born in Milan, Ohio on February 11, 1847. He was the youngest of seven children and received little formal schooling...
This is the first of two posts on the resistance of conductors. In the next post I will look at the ac resistance, including skin effect and we deal with...
This post is quick introduction and overview to different railway electrification voltages used in answer to a question sent in via email. While there...
Current transformers (CTs) are used to convert high level currents to a smaller more reasonable level for use as inputs to protection relays and metering...
