eQL quality meter
This group collects together electrical measurements of the commercial eQL Quality Meter manufactured by Electrix. The meter comprises advanced power quality features in addition to energy meter functionalities. The meter has been designed according to IEC 61000-4-30 Class S. The meter is able collect continuous measurement quantities and event data (voltage dips and swells, rapid voltage changes, disturbance recordings and interruptions). A general list of continuous measurement quantities of the meter is found below. Dataset specific measurement quantity lists may not include all of these measurement quantities.

- current
- active power
- fundamental frequency reactive power
- apparent power
- Fryze's reactive power (nonactive power)
- energy
- total distortion of voltage
- total distortion of current
- harmonic voltage (1st-40th order)
- harmonic current (1st-40th order)
- negative sequence component of voltage
