Electric power quality is the degree to which the voltage, frequency, and waveform of a power supply system conform to established specifications. Good power quality can be defined as a steady supply voltage that stays within the prescribed range, steady AC frequency close to the rated value, and smooth voltage curve waveform (which resembles a sine wave).

The Occupational Personality Questionnaires, OPQ or OPQ32, are widely used occupational personality questionnaires. The authors were Saville et al., including Roger Holdsworth, Gill Nyfield, Lisa Cramp, and Bill Mabey, and they were launched by Saville and Holdsworth Ltd. in 1984. [ 1 ]
The file format is designed to represent all power quality phenomena identified in IEEE Std 1159, [5] which is a recommended practice on monitoring electric power quality. PQDIF can be used to represent other power related measurement data and is extensible to other data types as well.

A rapid voltage change or RVC is one of the power-quality (PQ) issue related to voltage disturbance. "According to IEC 61000-4-30, Ed. 3 standard, RVC is defined as "a quick transition in root means square (r.m.s.) voltage occurring between two steady-state conditions, and during which the r.m.s. voltage does not exceed the dip/swell thresholds."
