Fundamental electrical engineering concepts and theory
How often installations are inspected is up to the owner of the installation, provided such durations do not exceed any regulatory maximums in force. ...
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...
Over the past year or so I've been involved in on going discussions related to referring fault levels from the secondary of a transformer to the primary...
Alternating current (a.c.) is the backbone of modern electrical power distribution. In this article I’ll be pulling some of the more important concepts...
The new standard IEC 61439 replaces the old 60439. Compared to the old standard, the new 61439 is a more clearly defined and takes into account the assembly...

This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
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...
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...
