Applications for the PowerVisa

Typical Applications

Equipment Performance Testing

Determining the availability and compatibility of facility power prior to the installation of new equipment is simplified using the PowerVisa 440. The instrument incorporates advanced features such as RMS triggers, low/medium frequency transients, and cross triggering between channels used to demonstrate that power mitigation devices such as UPSs are operating properly.

Energy Surveys

The PowerVisa 440 is an invaluable tool for performing energy surveys, including monitoring energy consumption, usage patterns, peak demands and the activation of large loads to reduce electricity costs.

Compliance Monitoring

The PowerVisa 440 has been designed to meet the most advanced power quality standards, including IEEE 1159, IEC 61000-4-30 Class A and EN50160.

Troubleshooting

The PowerVisa 440’s unique annunciator “report card” provides instant power quality answers in the field. Data is presented in color-coded categories to quickly identify areas of concern, identified in red. Drill down for more detailed information by simply touching the graphical screen.
