Capacitors are widely used in electrical engineering for functions such as energy storage, power factor correction, voltage compensation and many others...

Years ago I was told that you should always try to write the best report you can.  Many years later I still think on this as one of the better pieces of...

Working in the vicinity of electrical equipment poses an hazard. In addition to electric shock hazard, fault currents passing through air causes Arc Flash...

IEC 61439 'Low-voltage switchgear and controlgear assemblies', specifies standard arrangements of switchboard (call forms of internal separation). The...

From the earliest times, humans have found ways to create light. Pre-historic peoples used natural materials (moss, grass, etc.) soaked in animal fat and...

Fault calculations are one of the most common types of calculation carried out during the design and analysis of electrical systems. These calculations...

Installation of a UPS can help in reducing problems due to issues with the power supply.  A lot of people relate this to nine key issues.  Depending on...

Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...

A single phase system is perhaps the most common type of system most people are familiar with. This is what people have in their homes and what appliances...

Laplace transforms and their inverse are a mathematical technique which allows us to solve differential equations, by primarily using algebraic methods...
