To ensure their failsafe operation and compliance with safety and security standards our team of specially trained technical supervisors is ready to perform schedule maintenance and find tuning of the equipment hardware and software. At appropriate time our specialists will advise on all the necessary upgrades from the manufacturer.

Power Quality Analysis

Electrical grids are currently undergoing radical change. Big, conventional power plants are disappearing.

Phenomena such as backfeeding, equipment overloads, voltage spikes at feed-in points and asymmetries are part of day-to-day business. This is a problem for highly optimized data centres and industrial controls that are sensitive to short dips in supply, harmonics and transient events. Even the stability of the grid is vulnerable.
