Safety is at the heart of everything we do. We have a number of helpful hints to ensure farm workers can stay safe and avoid electrical hazards while working.
You care about the health and safety of your animals – and so do we. We want to make you aware of the potential dangers of stray voltage and the impacts it may have on your livestock.
What is stray voltage?
Varying amounts of low-level voltage may exist between the earth and electrically grounded farm equipment such as metal stabling, feeders, or milk pipelines. These voltages, known as “Animal Contact Voltage (ACV)”, “Stray Voltage” or “Tingle Voltage,” usually, present no harm. However, if the voltage level is high enough, they may affect livestock behavior and health.
What are the causes of stray voltage?
A variety of sources can cause stray voltage including: farm wiring and grounding issues, unbalanced farm load, equipment faults, or voltage from other sources such as telephone lines, gas lines and utility electrical distribution systems.
What are the Effects of Stray Voltage?
Tell-tale signs typically include cows being nervous at milking (especially in the milking parlors), cows refusing to enter the parlor and anxious to leave, increased frequency of defecation and/or urination in parlor as well as the reluctance to consume feed or water. Find more information on the effects of stray voltage on the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) website.
How do I reduce the impact of stray voltage?
If there is a source of stray voltage on your farm, you may perform mitigation measures such as installing a neutral isolating device, additional electrical bonding between contact points, wiring upgrades, or faulty equipment replacement. Be sure to have a qualified electrician perform the work and make sure it meets the requirements of the Electrical Safety Code. If the utility distribution system is the source of the Stray Voltage, the utility will take the appropriate corrective actions.
What do I do if I have a problem with stray voltage?
If you believe that you have a problem with stray voltage, please complete the Stray Voltage Investigation Request Form. All applications must be made in writing and be complete in order to process. We will contact you within five business days after you submit your application and provided a service order number. We will then notify you in advance to arrange the date of our first visit to your site.
