  2. PQDIF - Wikipedia

    en.wikipedia.org/wiki/PQDIF

    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.

  3. Comtrade - Wikipedia

    en.wikipedia.org/wiki/Comtrade

    The COMTRADE file format was standardized by the Power System Relaying & Controls Committee of the IEEE Power & Energy Society as C37.111. The original specification was published in 1991. The 1991 version specifies a file format that includes multiple file types designated by the assigned file extensions of *.CFG, *.HDR, and *.DAT.

  4. Electric power quality - Wikipedia

    en.wikipedia.org/wiki/Electric_power_quality

    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).

  5. Power-flow study - Wikipedia

    en.wikipedia.org/wiki/Power-flow_study

    In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as Voltage, voltage angles, real power and reactive power.

    IEC 60987 Nuclear power plants – Instrumentation and control important to safety – Hardware design requirements for computer-based systems; IEC 60988 Nuclear power plants – Instrumentation important to safety – Acoustic monitoring systems for detection of loose parts: characteristics, design criteria and operational procedures

  7. Condition monitoring - Wikipedia

    en.wikipedia.org/wiki/Condition_monitoring

    Handheld data collectors and analyzers are now commonplace on non-critical or balance of plant machines on which permanent on-line vibration instrumentation cannot be economically justified. The technician can collect data samples from a number of machines, then download the data into a computer where the analyst (and sometimes artificial ...

  8. Operations manual - Wikipedia

    en.wikipedia.org/wiki/Operations_manual

    It documents the approved standard procedures for performing operations safely to produce goods and provide services. [2] Compliance with the operations manual will generally be considered as activity approved by the persons legally responsible for the organisation. [3] The operations manual is intended to remind employees of how to do their job.

    These systems are widely employed for incoming inspection, quality assurance, and production testing of electronic devices and subassemblies. Industry-standard communication interfaces link signal sources with measurement instruments in “ rack-and-stack ” or chassis-/mainframe-based systems, often under the control of a custom software ...
