About Power Quality Monitoring
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 s et of electrically measured parameters which are typically
calculated based on some pre-defined intervals or event triggers and are evaluated
over a l arge observation window. For most of the PQ parameters, the observation
window is one week, which means the displayed o nline 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 n ational s tandards v ary t he w ay a s pecific P Q p arameter is b eing
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 in
order t o m eet n ew conditions, r ules, m easuring i ntervals, an d ev en d ifferent
observation periods.
