Revolutionary data compression technology takes the guess-work out of isolating the source of PQ problems by eliminating the need for devising set points and calculating threshold values. The ability to capture all the wave form data in high resolution in its entirety over an extended period of time is the only way to ensure that the event will be recorded, allowing the engineer to analyse the data and define a solution. Until now, monitoring and analysing system electrical trends have presented a true challenge because certain data compromises were required to counteract capacity, processing and physical limitations.
Data compression technology provides unlimited capacity for PQ data storage. This means that you are no longer required to set constraints on system data, rendering the risk in data selection based on set thresholds and triggers obsolete. Operators of electrical networks are constantly faced with power events and transient occurrences that affect PQ and heighten energy costs.
In the past, to determine whether such events reflect system trends or isolated incidents, electrical engineers relied on partial information indicating what events occurred and when; not all events were recorded due to data capacity limitations and missed thresholds. Now, by analysing multi-point, time-synchronised real-time PQ data, you can actually reveal why all power events occur and what causes them. In short, data compression technology pushes PQ analysis capabilities into the next generation.

- Data compression technology provides unlimited capacity for PQ data storage.
- Using data compression technology avoids capacity issues and therefore data is uncompromised.
