Electrical Substations are often located in areas with nearby residents and the steady "hum" at 120 Hz (and higher harmonics) can be considered quite annoying. Detailed site noise measurements, noise monitoring and noise modeling are often required to determine compliance with the Alberta Utilities Commission (AUC) Rule 012 and local municipal noise bylaws. Site specific noise mitigation is often required. ACI has the expertise and equipment to ensure regulatory compliance for electrical substations of all sizes.
ACI also has the capability to conduct detailed sound power level measurements of substation transformers in accordance with ISO 9614 and IEEE C57.12.90-2010
In addition ACI can conduct long term noise monitorings for several days up to several months and even permanent installations.
