Insulation on a motor prevents interconnection of windings and the winding to earth.  When looking at motors, it is important to understand how the insulation...

Circuit breakers are switching devices whose primary function is to isolate parts of an electrical distribution system in the even of abnormal conditions...

Electrical notes are a collaborative collection of electrical engineering information and educational material. Any registered user can add content. ...

Gauss's Electrical law defines the relation between charge ("Positive" & "Negative") and electric field.  The law was initially formulated by Carl Friedrich...

Cable insulation is used to provide electrical separation between conductors of  a cable.  During the historical development of cables, numerous types...

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...

Laplace transforms and their inverse are a mathematical technique which allows us to solve differential equations, by primarily using algebraic methods...

I have been thinking recently that there appears to be less professional integrity around than when I first started my career in electrical engineering...

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...
