Neighbors - Causes of Damaged Equipment and Solutions
There are several power disturbances that can be generated from one utility customer that may impact other customers. While these disturbances could use the utility lines to travel on, they might also be close enough to use nominal existing wiring. Neighbors include those in separate buildings near the customer and separate businesses under the same roof such as a small business park. Where there are separate offices inside one building, like independent lawyers sharing a single office building, then the discussions on internal causes and solutions better applies.
Three types of neighbor-induced disturbances are most common. They are transients from device switching, voltage sags, and voltage harmonic distortion.
