Power monitoring improves real-world maintenance programs

Power quality, Condition monitoring

The Fluke 3540 FC Three-Phase Power Monitoring sensor is easy to install and connects to Fluke Connect Condition Monitoring Software, keeping teams connected to assets to more quickly detect and troubleshoot problems.

The Fluke 3540 FC Three-Phase Power Monitor has improved the operational efficiency of many organizations. By implementing the 3540 FC into existing maintenance programs, organizations were able to cut costs, easily troubleshoot issues and prove their equipment failures were the fault of interrupted utility service.

3540 FC keeps problems in sight for optical industry

More than 64% of American adults wear eyeglasses. When the leader in optical machinery equipment, Optotech, started having power problems with equipment cutting lenses, they turned to power monitoring for a solution. By installing the 3540 FC, Optotech was able to discern why the equipment was having problems and how to repair it in a cost-effective way.

Using the Fluke 3540 FC Three-Phase Power Monitor, Optotech cut costs by more than $40,000 – totaling 300 hours of manpower alone, the cost of unnecessary replacement parts and the costs of technician travel.


“I can tell you, it’s paid for itself already.”

–John Marhefka, field service engineer at Optotech


On top of the cost savings, installing the 3540 FC was so easy and intuitive that Marhefka didn’t even need to wait for the instruction guide to implement the power monitor into Opotech’s maintenance program.

B3 Electric provides a full-service power consultation with the Fluke 3540 FC

B3 Electric, an industrial manufacturing power consultation company, uses the Fluke 3540 FC Three-Phase Power Monitor on equipment at client sites to improve processes in many ways, including:

Ensuring that clients are getting uninterrupted power from utilities

Improving power efficiency in assets

More easily identifying issues in assets, thereby reducing troubleshooting times

When a customer tells B3 Electric, “We suspect that we have a power issue; what can you do to help us identify that?” they have a response ready.

“I’m always very proud to say, ‘I have these two really cool meters from Fluke that I’ll hook up to remotely monitor your power,’” said John Baker, president of B3 Electric.

Power monitoring sensors warns maintenance teams of failures in health care equipment

The Fluke 3540 FC Three-Phase Power Monitor allows teams to view asset data from anywhere, at any time, allowing them to respond to changes in equipment condition within moments.

Marquis Medical was having problems with its power company where drops in power would damage components of vital CT machines. Other options for power monitoring devices required that an ethernet cable be hardwired, but the 3540 FC is wireless and needed no extra installation.

Shortly after deploying the 3540 FC, Marquis Medical was able to prove a drastic drop in supplied power. By gaining instant access to changes in asset condition via alarms on smartphones, Marquis Medical was able to run a report showing that power to the CT scanner dropped from 280 volts per leg to zero, and the power company was responsible for the damaged components.


“I have been using the 3540 FC Three-Phase Power Monitor for about [five] months now. I must say it’s an outstanding product. The app is great. I can get notifications and access it anytime and anyplace.”

–Matthew Turner, a field service engineer with Marquis Medical
