  • Metering and tariffs for harmonics
    The current flows into a meter due to harmonicvoltage distortion would increase the meter reading, and the idea of making a customerpay for harmonics NOT generated by the supplier , and usually damagmgfor the user, is perverse.
  • New notions suggested to power theory development part 2: A concept for sharing the responsibility of harmonics
    Standards [11]-[12] set out specific limits on harmonic distortion at the point of common coupling (PCC) between supplier and consumer of electric power. … consumer is a customer of the utility, and the PCC is a revenue meter in the secondary …
  • Glocalized Solutions for Sustainability in Manufacturing
    … temporal resolutions and are able to handle the high data output volume from the single metering equipment. Especially on unit process level, the harmonic distortion charge of the suppliers can be addressed, as the countermeasures can be applied directly at the source.
  • New power-quality assessment criteria for supply systems under unbalanced and nonsinusoidal conditions
    tests have proved that the proposed indexes can identify dis- torting and unbalanced loads on a network, provide reliable quantitative information about the level of harmonic distortion and unbalance, and separate the responsibilities of suppliers and users.

    The quality of power has high economic impact on utilities, their customers and suppliers of load equipment. Transients, long duration voltage variations, short duration voltage variations, voltage imbalance, waveform distortion caused by harmonics etc are some of the electromagnetic phenomena that cause power quality problems. Among these harmonic distortion has high impact on capacitors, transformers ,motors, energy and demand metering , Telecommunications etc.
  • A digital instrument for the calibration of current-to-voltage transducers
    In fact, the customer might not be the only one responsible for the harmonics passing through his meters ; therefore, the supply quality should be monitored also. Suitable methods are therefore required for monitoring electric power systems in order to provide the separation of the supplier ’s contribution to distortion from that of the customer.
