Electric Power Substation Fire Wall

FireWall for PSEG

There are several reasons to build walls around electric transformers. First is noise abatement. Electrical transformers radiate a low frequency hum at 120 Hz (two times the 60Hz AC power frequency) and harmonics at 240 Hz, 360Hz, 480 Hz, etc. Walls perform as noise barriers to block the direct propagation path from the transformer to […]
