South Dakota § 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.
