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).
A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%).
Process performance qualification protocol is a component of process validation: process qualification.This step is vital in maintaining ongoing production quality by recording and having available for review essential conditions, controls, testing, and expected manufacturing outcome of a production process.

U.S. federal government agencies use PQubes to detect power quality issues – for example, the Federal Aviation Administration tracks disturbances at radar control centers. [ 7 ] Each PQube instrument is traceable to the National Institute of Standards and Technology , so often these instruments are used in international academic and research ...
