Electrical equipment - design, use and implementation
The calculation of current in a three phase system has been brought up on our site feedback and is a discussion I seem to get involved in every now and...
When making adding a Note to our site we have a great online WYSIWYG editor and things are pretty simple. However, if you prefer you can write, manage...
Many questions sent in to the site are in connection with motor starting and in particular star-delta. For all but the simplest application, there is...
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...
One of the fundamental requirements of an alternating current distribution systems it to have the ability to change the magnitude of voltages. It is more...
Low voltage (LV) switchrooms are common across all industries and one of the more common spatial requirements which need to be designed into a project...
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...
Modelica is an open source (free) software language for modelling complex systems. Having never used it before, I thought I would download a development...
Request to look at induction motor starting time have come up a few times on the site. Hopefully in this post, I give you guys some idea on how to calculate...
One of the comments on my Motor Starting Series was asking for something on duty cycles. Here it is. As a purchaser of a motor, you have responsibility...
