One of the most common metrics for measuring efficiency in facilities that host data centers for financial, insurance and telecommunications facilities is a power usage effectiveness (PUE). Electrical distribution system losses account for 12% of the total energy consumed by the data center. In addition, unscheduled downtime in a data center is now estimated to cost over $8,000 per minute – not to mention the reputational damage to the data center company. One method for increasing reliability is to implement Electrical Maintenance Safety Devices (EMSDs) such as
infrared windows, ultrasound ports, voltage detection ports and online monitoring to allow energized electrical maintenance tasks to be completed safely and efficiently.
