A quieter transformer station thanks to sound dividers
A transformer station in the north of Brabant didn’t comply with the sound-technical permit requirements anymore. The station’s neighbours, who live just a few hundred metres away, had started to complain to the municipality about the noise pollution. The transformers were built in 1968 and are all scheduled to be replaced in a few years. But as the noise complaints were increasing, a solution was needed now. Therefore Merford decided to come up with a temporary solution to help the neighbours enjoy the region’s peace and quiet once again.

The client’s most important requirement was that the current installation would be altered as little as possible. A construction calculation and an acoustics design aided Merford to map out the ideal approach. For each transformer cell, totalling six, Merford created a 21 metre long construction of G14/EP type sounds panels. These panels are made of mineral wool with a glass fleece and both blind and perforated aluminium plates. In order to provide ample space for the high-voltage components, the wall varies between 3.2 and 5 metres high.
Measurements
Taking the replacement of the transformer stations in the future into account, the wall elements have been made in such a way, they can easily be dismantled and reused. The walls contain sound insulation doors which allow for easy access to the transformer stations in case maintenance has to be carried out. This entire project turned out to be very successful as the sound pollution is now well within the limits that the permits require on every single measuring point.
