X/R is critical for short circuit analysis, but we can understand so much more when we think in terms of time constants.

Differential Protection picks up the slack where traditional Overcurrent Protection can't get the job done

Introduction - Cable ampacity (how many amps a particular cable type can carry) is one of the most important design calculations....

Intro - In a perfect world, transformers convert from one voltage level to another without any impact on the system. Unfortunately, this...

Intro - When power systems engineers refer to "transformers", we're almost always talking about a particular subset: 2-winding...

Introduction - Line to line faults are a common type of short circuit event on a power system. During line to line faults, one phase...

Introduction - Single line to ground faults are the most common type of fault in a power system. On overhead transmission and...

Introduction - Suppose you've got a power distribution system with some loads fed from a source. But then, OH NO!! A fault takes place on...

Lightning strikes on power systems are common. A storm is overhead and lightning attempts to find the easiest pathway to ground. This...

General - Motors are magnetic devices. They rely on the interaction between magnetic fields to create rotation. Before this rotation...

Electricity is dangerous-plain and simple. The world has become electrified and electricity has almost universally improved the standard...
