Section 113.0701. Definitions.

  In ss. PSC 113.0701 to 113.0707 , the following definitions apply:

(1)  "Flicker" or "voltage flicker" means a variation of input voltage sufficient in duration to allow visual observation of a change in electric light intensity.

(2)  "Harmonic distortion" means the mathematical representation of the distortion of the pure sine waveform. Distortion of the pure sine waveform is typically caused by loads that draw current discontinuously or whose impedance varies during the cycle of the input ac voltage waveform.

(3)  "Point of service" means the connection point between the customer electrical system and the utility electrical system.

(4)  "Power quality" means the concept of powering and grounding sensitive electronic equipment in a manner that is suitable to the operation of that equipment.

(5)  "Retail power service" means service furnished principally for electromotive or industrial purposes and may include service for lighting incidental thereto, as defined in the utility's rates and rules.

(6)  "Sag" means an rms reduction in the ac voltage, at the power frequency, for durations from a half-cycle to a few seconds.

(7)  "Swell" means an rms increase in the ac voltage, at the power frequency, for durations from a half-cycle to a few seconds.

(8)  "Transient" means a subcycle disturbance in the ac waveform that is evidenced by a sharp but brief discontinuity of the wave form. A transient may be of either polarity and may be additive to or subtractive from the nominal waveform.

(9)  "Steady state voltage" means the rms voltage after all sags, swells and transients have decayed to a negligible value.

(10)  "Service voltage" means the steady state voltage at the point of service.
