An official IEEE document at any point in time consists of the current edition of the document together with any amendments, corrigenda, or errata then in effect.Every IEEE standard is subjected to review at least

25、every 10 years. When a document is more than 10 years old and has not undergone a revision process, it is reasonable to conclude that its contents, although still of some value, do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest ed

By publication of this standard, no position is taken by the IEEE with respect to

29、 the existence or validity of any patent rights in connection therewith. If a patent holder or patent applicant has filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE-SA Website at http:/standards.ieee.org/about/sasb/patcom/patents.html. Lett

The IEEE is not re-sponsible for identifying Essential Patent Claims for which a license may be required, for conducting inquiries into the legal validity or scope of Patents Claims, or determining whether an

Users of this standard are expressly advised that determination of the valid-ity of any patent rights, and the risk of infring

All rights reserved.IntroductionThis introduction is not part of IEEE Std 1695-2016, IEEE Guide to Understanding, Diagnosing, and Mitigating Stray and Contact Voltage.For many years

42、 the term stray voltage had been primarily used to discuss the power frequency voltages present at animal contact locations in and around animal confinement facilities. With the widespread availability of in-expensive and user friendly voltage measurement and recording devices, there has been a grow

43、ing awareness that the general public and their pets are also regularly exposed to these voltages at many publicly and private-ly accessible locations. Until recently there has been little recognition of the important difference between the presence of small voltages related to normal electrical sys

44、tem operation (customer and utility) and the pres-ence of potentially harmful and even lethal voltages related to un-cleared electrical faults. This guide has been created because there are few easy to understand public documents that describe the phenomena, their causes and effects, and actions tha

45、t may help identify and reduce potentially dangerous voltage conditions.This guide does not reflect the views of any one contributor or source and is not intended for use to advance a specific scientific, public health, security, environmental, or legal position attributed to, or propounded by, any

46、user or third party. While it is impossible to give recognition to all those who have contributed to the content of this guide, the assistance of past and present members of the IEEE PES T phase conductor faults and neutral conductor faults. Contact voltage often results from damaged insulation on p

47、hase conductors or dam-aged or faulted neutral conductors. Improperly connected customer or utility equipment can also cause contact voltage. Since contact voltage often involves phase conductors, it should be treated carefully because a low voltage level can rise to full line voltage as the impedan

48、ce of the conductive fault pathway changes.Contact voltage is not a traditional step and touch potential problem. Step and touch potentials are usually discussed in terms of the accessible voltages present during a short duration electrical system fault event. The risk of contact voltage is not just

49、 from the momentary voltage associated with a short duration fault, but rather the presence of an electrical fault in customer or utility wiring that has not cleared (i.e., the protection device, if present, has not operated). As such, the fault can result in a long term publicly accessible voltage that may, under specific exposure conditions, reach harmful levels. Based on utility experience, in the majority of cases the voltage measured at the time of investigation is in excess of 5 V, but many cases are reported below 5 V (New York State Public Service Commission B35).
