Chapter 47 - Stray Electrical Current And Voltage Remediation
Section 49-47-1 - Definitions.

49-47-1. Definitions.
Terms used in this chapter mean:
(1)"Adequate remediation," corrective action by an electric utility that results in, and is reasonably likely to sustain, a reduction of stray current or voltage attributable to the electric utility's distribution system of fifty percent or less of the preventive action level;
(2)"Commission," the Public Utilities Commission;
(3)"Cow contact points," any two electrically conductive points that a dairy cow may, in its normal environment, unavoidably and simultaneously contact;
(4)"Electric utility" or "utility," an electric utility as defined in §49-34A-1;
(5)"Preventive action level," stray current or voltage that is either:
(a)A steady-state, root mean square (rms), alternating current (AC) of 2.0 milliamp (mA) or more through a 500 ohm resistor connected between cow contact points, as measured by a true rms meter; or
(b)A steady-state, rms, AC voltage of 1.0 volts or more, across (in parallel with) a 500 ohm resistor connected between cow contact points, as measured by a true rms meter;
(6)"Steady-state," the value of a current or voltage after an amount of time where all transients have decayed to a negligible value;
(7)"Stray current or voltage,":
(a)Any steady-state, 60 hertz (Hz) (including harmonics thereof), root mean square (rms), alternating current (AC) of less than 20 milliamp (mA) through a 500 ohm resistor connected between cow contact points, as measured by a true rms meter; or
(b)Any steady-state, 60 Hz (including harmonics thereof), rms, AC voltage of less than 10 volts, across (in parallel with) a 500 ohm resistor connected between cow contact points, as measured by a true rms meter.
