The Basics of Stray Current

CORROSION 1969, 1969
All corrosion is the result of an electrochemical reaction; it involves both electrical and chemical events. For electrochemical corrosion to occur there must be a potential difference between two points that are electrically connected and immersed in an electrolyte.

Parametric Stray Current Monitoring and Mitigation for Electric Rail Stray Current

CORROSION 2005, 2005
Abstract Built in several stages over 20 years, the electric rail system in Portland, Oregon is varied in construction design and materials and presents a range of stray current conditions. The rail system is proximate to water supply mains, distribution mains, and services also constructed with varied materials and methods.

Measurement and Analysis of Stray Currents

2019 20th International Scientific Conference on Electric Power Engineering (EPE), 2019
Nowadays, the issue of stray currents is very actual, especially due to origin of electrochemical corrosion of storage devices. The biggest sources of stray currents are direct current traction systems such as railways and city lines using rails as a return conductor. In many cases, the return current does not flow back to traction converter substation

Stray Current Corrosion - Aluminum

CORROSION 1975, 1975
This paper covers one phase of a systematic study of the effects of stray current on engineering materials conducted at the Naval Research Laboratory over the past two years. Parameters that might be used in detection of stray current have also been studied.

Stray current analysis

2011 IEEE IAS Electrical Safety Workshop, 2011
Stray currents, sometimes called “objectionable currents” are part of the same phenomenon called “stray voltage.” Stray currents can cause electric shocks to humans in swimming pools. Stray voltages caused by the multigrounded neutral system can have severe effects on both humans and farm animals.

Stray Current Aspects of Bart

CORROSION 1974, 1974
Many people are watching the startup of the 75 mile BART d-c powered transit system, and no one has taken a keener interest in BART operations than the owners of underground structures. This paper is divided in five parts each of which discusses effects of BART operation on a particular type of underground facility.
