Prevent stray voltage on publicly accessible infrastructure

Walker Engineering recognized by ESA in fight against potentially fatal stray voltage.

Point Pleasant, N.J.—Walker Engineering, a small engineering and construction firm in New Jersey, has recently been recognized by the Electrical Safety Authority (ESA) of Toronto, Canada, as a key partner in the fight against potentially fatal stray voltage. In their formal guideline for the “Electrical Design, Installation, Operation, and Maintenance of Street Lighting Assets”, the ESA highlights Walker Engineering’s Handheld Contact Voltage Detector as an “ideal tool for verifying a reference (street pole) is not energized, indicating zero electric field”.

The guidelines were written in response to the increased amount of attention paid to the condition of low voltage electrical distribution systems, including those supplying streetlights. This can be attributed to a number of high-profile incidents where members of the public have reported receiving an electric shock after coming into contact with publicly accessible infrastructure. The consequences of these incidents range from pedestrians reporting a “tingling” sensation to cases which have resulted in a fatality.

Walker’s Contact Voltage Detector is meant to detect the presence of voltages on structures that are supposedly voltage free such as light poles, fences, doors and literally any structure that can be contacted by an electric source. When held in the vicinity of a voltage potential, the instrument indicates the relative field strength of the surrounding electric field giving notification to the operator of its presence. The Contact Voltage Detector is a valuable tool for technicians who need to determine the safety of the environment, or the validity of a true ground.
