  2. 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).

  4. Conducted emissions - Wikipedia

    en.wikipedia.org/wiki/Conducted_emissions

    It measures power quality of AC mains for different voltage levels as described in common EMC test standards. By definition, the AC harmonic is a multiple of the electrical quantity (voltage or current) at multiples of the fundamental frequency of the system, produced by the action of non-linear loads such as rectifier , lighting , or saturated ...

  5. Voltage optimisation - Wikipedia

    en.wikipedia.org/wiki/Voltage_optimisation

    Voltage optimisation is a term given to the systematic controlled reduction in the voltages received by an energy consumer to reduce energy use, power demand and reactive power demand. While some voltage 'optimisation' devices have a fixed voltage adjustment, others electronically regulate the voltage automatically.

  6. Power conditioner - Wikipedia

    en.wikipedia.org/wiki/Power_conditioner

    A power conditioner (also known as a line conditioner or power line conditioner) is a device intended to improve the quality of the power that is delivered to electrical load equipment. The term most often refers to a device that acts in one or more ways to deliver a voltage of the proper level and characteristics to enable load equipment to ...

  8. Signal integrity - Wikipedia

    en.wikipedia.org/wiki/Signal_integrity

    Signal integrity or SI is a set of measures of the quality of an electrical signal. In digital electronics , a stream of binary values is represented by a voltage (or current) waveform. However, digital signals are fundamentally analog in nature, and all signals are subject to effects such as noise , distortion , and loss.

  9. Sulfur hexafluoride circuit breaker - Wikipedia

    en.wikipedia.org/wiki/Sulfur_hexafluoride...

    Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit. Advantages over other ...
