Just added a page to the tools, which will allow you to calculate the synchronous speed, slip and rated torque for an induction motor. Not a particularly...

In three phase systems, the use of transformers with three windings (or legs) per side is common.  These three windings are often connected in delta or...

In electrical engineering, Network Theory is the study of how to solve circuit problems. By analyzing circuits, the engineer looks to determine the various...

Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...

Photovoltaic (PV) systems are typically more efficient when connected in parallel with a main power gird. During periods when the PV system generates energy...

Control theory looks at how systems work and are controlled from a mathematical view.  This note gives a brief introduction to some of the concepts – more...

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

This is the second post in a series of two on periodic electrical inspections. In the first post, I discussed how often inspections should be carried out...

Anyone specifying or using electric motors should have a basic understanding how the insulation is related to temperature. Three classes of insulation...
