While all electronic equipment is designed to handle varying voltage within a specified range, voltage events become a concern when they exceed designed tolerances. The Voltage Performance Monitor (VPM) from IDEAL quickly and accurately identifies voltage events and harmonics that cause IT equipment damage or failures.
"Our VPM tells the technician if problematic voltage events on the circuit are occurring and logs the time, duration, and severity of the event," explained Dave Skowronski, Product Manager for IDEAL. "It gives technicians the power to quickly determine if an equipment problem is related to voltage and if a circuit is safe for new or existing equipment, such as computers, copy machines, or servers. It also lets a technician easily verify the need for a UPS installation or a surge protective device, as well as confirm the protection provided by such equipment."
Because the VPM plugs directly into a circuit at the point of equipment connection, it will "see" exactly what the equipment sees. Logging only those events that exceed designed tolerances, including voltage sags, swells, impulses and excessive Total Harmonic Distortion, the VPM determines if equipment failure is related to a specific voltage event. Time and severity of events are displayed on its bright OLCD screen that inverts when it is necessary to plug-in upside down. Up to 512 events can be stored in the unit's internal memory for review by category or chronological order.
The VPM comes pre-loaded with tolerance settings based on 15 internationally recognized standards including ITIC, CBEMA, SEMI and ANSI. Users simply select the appropriate standard for the application and the VPM logs those events while ignoring the rest. Technicians can also set their own custom thresholds to meet specific needs.
Sources of Voltage Problems
The source of 85% of all voltage events originates within a facility. Voltage events can be caused by inadequate supply, undersized wiring, an overloaded circuit, and frequently by other equipment turning "on" or "off" on the same circuit. Voltage quality also changes every time a new piece of equipment is installed in a facility or in a neighboring facility. In addition, voltage events are caused by environmental changes, such as lightning storms, high winds, flooding, physical damage, or utility operations.
