Speed of Line Protection – Can We Break Free of Phasor
... In his 1883 paper, Léon Charles Thévenin taught that any linear stationary dc network can be represented—for any two terminals in the network—by an equivalent source and an equivalent resistance. Later on, capitalizing on Steinmetz’s work on ac networks, Thévenin’s theorem was extended to ac network ...

Stray voltage
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
