Power disturbances can have numerous effects on sensitive electronic equipment, including data errors, system halts, memory or program loss, and equipment failures. Since it is often difficult to determine whether these problems are caused by power disturbances or by unrelated electronic equipment or software failures, a power system survey and analysis could be required. The analysis should be performed by professionals and should determine, at minimum, the following:
The soundness of the power distribution (wiring) and grounding systems supplying power to the equipment
The quality of the AC voltage supplying power to the equipment
The source of power system disturbances
The impact of power disturbances on data center equipment ...
