Some farms have overhead power lines crossing their property. You don't have to touch a power line to be electrocuted. Even coming close can cause the electricity to jump between the wire and material that conducts electricity, such as farm equipment, ladders, tree limbs and even hay, under certain conditions.
See the Electrical Safety Authority's Farm Safety Tips.

Varying amounts of low-level voltage often exists between the earth and electrically-grounded farm equipment, such as metal stabling, feeders, or milk pipelines. The voltage that causes this small current is known as "animal contact voltage", "stray voltage" or "tingle voltage". Usually, these voltage levels present no harm, however, at high enough levels, these stray voltage may impact the health and behaviour of livestock.

More information about Stray Voltage can be found on the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) website.
If you think you have a stray voltage problem affecting your livestock, or if you have any questions or concerns about the electrical service on your property, please submit a Farm Stray Voltage Reporting form, or contact our Customer Care Team.
