Voltage Performance Monitor

Professional and accurate voltage analysis made easy

Through easy-to-navigate setup, select from a menu of pre-set standards, plug it into the outlet and watch the unit capture and log voltage events. All the information you need is at your fingertips presented on a super-bright OLED display. Using the Voltage Performance Monitor (VPM) is the easiest way to know the reliability of your voltage.

Features:

• Real-time TRMS voltage, frequency and harmonics monitoring
• Logs voltage, sags, swells and impulses
• Measures %THD and logs periods over 3% (line to neutral)
• Selectable thresholds based on the most accepted international standards, defaults to ITIC*
• Custom programmable event thresholds
• Invertible display, when it is necessary to plug in upside down
• Saves up to 512 events
• CAT III 300V

Applications:

• Monitor voltage near sensitive equipment
• Installation and Service Technicians
• Monitor voltage at point of equipment connection
• Electricians
• Eliminate guesswork on service calls
• Building Maintenance Technicians
• Identify voltage caused equipment failures
• Equipment Manufacturers
• Eliminate unnecessary warranty costs
• Hospital/IT Maintenance Engineers
• Monitor voltage quality to critical equipment

See voltage through the eyes of your equipment

Poor voltage quality is expensive.

When a voltage problem is suspected, the first approach has been to place an analyzer on the main service. This approach misses problems at the branch level. The VPM works where symptoms occur—at the point where equipment is connected. Poor voltage quality increases facility expenses, warranty costs and downtime plus shortens the life of equipment. The IDEAL VPM identifies voltage conditions that can damage equipment or cause equipment failure.

Equipment is designed to handle varying voltage within a specified range. Voltage events become a concern when they exceed designed tolerances. VPM only captures events that go beyond internationally recognized tolerances, specifically those that are likely to cause equipment problems. Now you have the ability to determine if a failure is related to a voltage event that originated from a utility or other nearby source. You can also determine if voltage is stable enough to add sensitive equipment.

Additionally, you can easily and quickly determine the need for power conditioning equipment such as a UPS installation or a surge protective device as well as verify the protection provided by such equipment.

Voltage Events

Voltage events are defined in terms of magnitude and duration. Magnitude is the deviation from nominal voltage (in percent) of the event and duration is the length of the event. The most important events for equipment performance are sags, swells, impulses and total harmonic distortion. The VPM uses pre-set thresholds to log events that affect equipment and ignore those that don’t.

Harmonics

Harmonics are the components of voltage distortion. Distortion of the voltage sine wave is measured as total harmonic distortion. A small amount of distortion will not affect equipment performance. Higher levels of distortion will cause many equipment problems. On branch circuits, levels of harmonics greater than 5%–8% associated with equipment problems need further investigation.

Standards and Event Thresholds

The most accepted worldwide standards are pre-loaded on the IDEAL VPM. You can select the appropriate standard for your application or location. A custom option even allows you to set your own thresholds. The optimum standard to use depends on whether you are only concerned with major events and interruptions or you have equipment and processes that are more sensitive to voltage fluctuation. The default thresholds are based on the Information Technology Industrial Council (ITIC) standard. The ITIC standard is designed to capture events on single phase branch circuits supplying power to computers, copiers, gaming machines and other sensitive electronic equipment. Other integrated standards include ANSI, IEEE1159, CBEMA, SEMI, IEC-61000-2-4, IEC-61000-4-11, EN50160, EN5082-1, MIL STD 704E Aircraft, MIL STD 1399 Shipboard, ZA South Africa, JN Japan.
