It is estimated 30-40% of unscheduled downtime is due to power quality issues such as voltage sags and swells.

Are you aware what critical equipment you run is affected by power quality?

ABB’s PCS100 AVC-40 is a high performance power electronic system designed for industrial and large commercial applications. It responds instantly to power quality events, providing continuous regulation of voltage.

With high power capacity, the PCS100 AVC-40 is the perfect solution for industrial loads using significant power as well as large commercial buildings where continuity of service is paramount. The PCS100 AVC-40 is designed to target voltage sag events while also providing protection against swells. Sag events are the major cause of lost production.

PCS100 AVC-40 Correction Capabilities

The PCS100 AVC-40 responds to voltage sags or swells within several milliseconds and can inject up to 40 percent voltage correction. If a facility was faced with a voltage sag to 60 percent of nominal voltage the PCS100 AVC-40 would boost the voltage back to 100 percent. Voltage sags with 50 percent of nominal voltage are corrected back to 90 percent. No process interruption, no equipment would trip, just business as usual. No Costly loss of production.

Performance is even better for single phase sags (the most common type), voltage sags down to 45 percent of the nominal voltage are fully corrected

In case of deeper voltage sags, The PCS100 AVC-40 undertakes a partial correction, which will often prevent loads tripping. In addition, it is able to continuously correct voltage fluctuations of ±10 percent of nominal, remove imbalances and mitigate flicker from the supply voltage.

How it works

The PCS100 AVC-40 consists of two converters that are not on the current path between the load and the utility. Instead, the corrective voltage injection is achieved by means of a transformer winding between the utility and the sensitive load.This configuration results in a very efficient and effective method to provide voltage correction with reduced risk of negative impacts on the load.

The PCS100 AVC-40 requires no batteries as it draws the additional energy required during sag to make up the correction voltage from the utility supply. With no ongoing maintenance costs typically associated with batteries the cost of ownership for PCS100 AVC-40 systems is very small.
Furthermore, the PCS100 AVC-40 contains a redundant internal bypass system that, in the event of overload or internal fault condition,ensures that the load is continued to be supplied from the utility.

Key benefits
Reduce the cost of sag events
The PCS100 AVC-40 closes the electrical compatibility gap between the supply and plant by protecting the load from utility induced voltage sag events. The PCS100 AVC-40 minimizes the undue stress to the expensive equipment, thus increasing the equipment lifetime.
