Section R. 460.2702 - Measuring animal contact voltage
Universal Citation: MI Admin Code R. 460.2702
Current through Vol. 24-16, September 15, 2024
Rule 2.
(1) A utility shall respond to a request for investigation and work with the complainant to conduct an initial investigation to determine stray voltage levels. If resolution is not met, the complainant may request further investigation as provided for in this rule.
(2) Upon conclusion of (1) and upon request of the complainant, a utility shall conduct an investigation of each complainant inquiry or complaint concerning animal contact current or voltage, commonly referred to as stray voltage. The following shall apply:
(a) The level of animal contact current shall
be determined from measurements of animal contact voltage using Ohm's Law. The
voltage measurement shall be made between 2 points, which an animal can
simultaneously contact and under which animal contact voltage is most likely to
occur. When measuring from the floor or earth, a single metallic plate with an
area of 12 to 16 square inches shall be used to simulate the foot of the
animal. One lead of the measuring instrument shall be connected to the plate,
which shall be placed on the floor or earth where an animal may stand. The
other lead of the measuring instrument shall be connected to a conductive
object that an animal could reasonably contact while 1 of its feet is at the
location of the plate. For all measurements of animal contact voltage a shunt
resistor shall be used to simulate the resistance of the animal. A suitable
material, such as a medical grade electrode contact gel, shall be used to
simulate real conditions and maintain conductivity to the floor or earth for
the duration of the testing period.
(b) An approved method for determining the
utility contribution to the animal contact current is contained in
R 460.2707, Protocol to Evaluate
Utility Contribution to Animal Contact Current.
