PQDIF is defined in a "recommended practice" standard maintained by the IEEE PQDIF Task Force, [4] which is sponsored by the Transmission & Distribution Committee of the IEEE Power & Energy Society. The file format is designed to represent all power quality phenomena identified in IEEE Std 1159, [5] which is a recommended practice on monitoring ...
The site is updated approximately every 2 minutes with worldwide power quality and energy recordings. Data from these PQubes can be used, for example, for developing and testing power quality algorithms. [11] [12] [13] Available data include daily, weekly, and monthly files in GIF and Microsoft Excel CSV format. Voltage and current ...
The standard is for files stored on currently used physical media such as portable external hard drives, USB drives, CD, or DVD. The file format called Power Quality Data Interchange Format (PQDIF) is similar to COMTRADE in structure but is used primarily to convey power quality data instead of transient disturbance data. Like IEEE COMTRADE ...
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).
