About Monitoring Power Quality
The BLACKBOX contains a power quality compliance engine that enables real-time evaluation of
power quality according to standards such as EN50160. Power Quality (PQ) Compliance is a set of
electrically measured parameters which are typically calculated based on some pre-defined
intervals or event triggers and are evaluated over a large observation window. For most of the PQ
parameters, the observation window is one week, which means the displayed online information
refers to the previous week. However, using ELSPEC's PQSCADA and Investigator applications, all
time intervals are able to be observed.
A PQ parameter is typically based on a power quality event. For example, the DIP PQ parameter is
based on counting DIP events over some observation period.
Different national standards vary in the way a specific PQ parameter is being measured or observed.
The PQ Engine also supports a mode that can be customized by the user, in which all compliance
parameters can be self-edited and modified by a user in order to meet new conditions, rules,
measuring intervals, and even different observation periods.
The Power Quality section in Elspec's Web Interface is used to control and view power quality
measurement and compliance information computed by the PQ Engine that includes:
