eQL quality meter

This group collects together electrical measurements collected with the commercial eQL Quality Meter. eQL is an advanced power quality meter. It collects basic electrical measrurements such as power, current, voltage and cumulative energy, but also advanced power quality measurements such as symmetrical components of voltage, and voltage and current harmonics up to 40th order.

Here is a list of some of the more commonly used measurements with their names and descriptions. These measurement names can be found from the lists of available measurements for the datasets in this group.

• freq: frequency
• P: active power
• EP+: Total amount of energy produced or consumed since the metering was started until the current measurement time.
