TITLE 61

PUBLIC UTILITY REGULATION

CHAPTER 8

STRAY CURRENT AND VOLTAGE REMEDIATION ACT

61-802.  Definitions. As used in this chapter, unless the context otherwise requires:

(1)  "Adequate remediation" means corrective action by a utility which results in, and is reasonably likely to sustain, a reduction of stray current or voltage attributable to the utility’s distribution system of fifty percent (50%) or less of the preventive action level.

(2)  "Commission" means the Idaho public utilities commission as established pursuant to section 61-201, Idaho Code.

(3)  "Cow contact points" means any two (2) electrically conductive points which a dairy cow may, in its normal environment, unavoidably and simultaneously contact.

(4)  "Preventive action level" is 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.

(5)  "Steady-state" is the value of a current or voltage after an amount of time where all transients have decayed to a negligible value.

(6)  "Stray current or voltage" is:

(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. Stray current or voltage is a normal, inherent and unavoidable result of electricity traveling through grounded electrical systems, including a dairy producer’s on-farm system and a utility’s distribution system, which systems are required by the national electrical code and the national electrical safety code to be grounded to the earth to ensure continuous safety and reliability.

(7)  "Utility" means a public utility as defined in section 61-332A, Idaho Code.
