Issue:
Transformer sound levels
Product Line:
LV Transformers
Environment:
Applies to Low Voltage Transformers by SquareD/Schneider Electric
Resolution:
Low Voltage Ventilated and Non Ventilated Transformer Installers should be sure to fully loosen the core and coil mounting nuts in each corner of the Transformer assembly to allow the rubber sound/vibration dampening pads to work properly.
(Refer to page 25 of the attached bulletin).
Transformers are allowed, by NEMA standards, a certain amount of normal operating sound level which varies with kVA size. If you think your Transformer exceeds these allowable limits then contact your local Schneider Electric Distributor. There is no dependable or safe way to reduce the actual sound level of the transformer at the job site. However, sound can be amplified by reflecting hard surfaces near Transformers. Acoustical treatment of these surfaces, or reorientation of the Transformer can sometimes reduce objectionable noise. Schneider Electric can offer an engineered, reduced sound level Transformers on a special order basis. Contact your local Distributor for more information.
