EM Energy Solutions just recently completed an extensive power quality survey at four boreholes in the outskirts of London. The water utility company struggled with the unreliable operation of the pumps supplying water to the area. The unreliable operation required many resources from the water utility company in terms of maintenance, support, and meeting customer demands.

After six months of continuous power quality monitoring, we could give the customer a detailed overview of the problem and frequency of events. It was proven that the problem was due to random voltage sags coming from the DNO side. To protect against these adverse abnormalities, EMES proposed a tailor-made solution including our Ride Through Storage system. This will ensure a safe and reliable operation for years to come.
