Reducing Equipment Downtime and Improving Energy Efficiency via Wireless Power Monitoring

Equipment failure is a large part of unplanned downtime, slowdowns and/or loss in quality of the product being produced. Monitoring temperatures, vibration, differential pressures across filters are often performed to identify problems before failure occurs.

Another important set of measurements that can provide early warning are the voltage, current and other electrical parameters on the motors driving equipment such as pumps, fans, compressors, etc.

In this short 1:55 YouTube video, Emerson’s Matt Austin describes how these electrical parameters can be monitored and reported wirelessly via WirelessHART communications back to the control and asset management systems to provide early warning of abnormal conditions.

Matt opens the video describing how the 56WM Wireless Power Meter can be applied to programs to improve equipment reliability and energy efficiency. Real-time energy consumption and demand data at the equipment level provides feedback to optimize energy usage.

These power meters have been deployed in many industries including refining, steel production, offshore oil & gas production and even aboard cruise ships.

The Wireless Power Meter is designed to monitor voltage, current, power, energy, and other electrical parameters on single and three phase electrical systems with revenue-grade accuracy. It supports application loads up to 600 volts and 4000 amps. The power meter runs on the AC line power so batteries are not required. The list of measured variables includes volts, amps, kW, kWh, kVAR, kVARh, kVA, kVAh, apparent power factor, and displacement power factor—measured within 0.2% accuracy.

Current transformers connect to the Wireless Power Meter to measure current flow and to monitor the load. Voltage connection points are available for up to 3-phase voltage and neutral connections. The wireless antenna is built with a removable design for remote antenna mount or high-gain antenna options.
