A frequent problem in fault calculations is the obtaining of equipment parameters.  While it is always preferable to use the actual parameters of the equipment...

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...

When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...

It's been a busy few months on different projects or busy couple of decades depending on how I look at it. I can say that on the odd (frequent) occasion...

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...
