Cable insulation is used to provide electrical separation between conductors of a cable. During the historical development of cables, numerous types...
Installation of a UPS can help in reducing problems due to issues with the power supply. A lot of people relate this to nine key issues. Depending on...
Following on from my post on railway electrification voltages, I thought an introduction to traction substations would be a good idea. Traction substations...
Power factor is the ratio between the real power (P in kW) and apparent power (S in kVA) drawn by an electrical load. The reactive power (Q in kVAr)...
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...
Electrical engineering is a field that covers a wide variety of sub-fields, including electricity and electronics. It is a field that goes back to the...
Often document control is dictated by project requirements, for example a particular organisation may have an existing numbering system. Existing company...
Photovoltaic (PV) cells (sometimes called solar cells) convert solar energy into electrical energy. Every year more and more PV systems are installed...
