This article gives an introduction to IEEE 485 method for the selection and calculation of battery capacity.
If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...
Various arguments exist around SF6 Gas Insulated (GIS) and Air Insulated (AIS) medium voltage switchgear. Recently we had to change a GIS design to AI...
If you have a great idea or invent something the last thing you want is someone to steal the idea. One of the things you can do is protect the intellectual...
