Fluke 3540 FC Three-Phase Power Monitor
The 3540 FC Three-Phase Power Monitor is a compact device to monitor key electrical parameters at three-phase machinery (or equipment) and stream data to the Fluke Connect® Cloud. The measurement data is available on any connected device using Fluke Connect mobile app or Fluke Connect® Condition Monitoring software.
Graphs are available to show the trends and fluctuations of the measurements during the monitoring period. Alarm settings notify users immediately when measurement values are outside specified thresholds.
Monitoring the electrical parameters like current and distortion can reveal how the machinery (or equipment) is performing, for example:
- A baseline current or load at a critical pump is trending dangerously close to the motor’s maximum current rating, taking service factor into account.
- The total power at an induction furnace appears to be fluctuating abnormally during a curing cycle.
- Determining how often a submersible or hydraulic pump is cycling on/off to maintain flow or pressures, in some cases simply validates their is power to the pump.
Immediate access to information about machinery performance can be the difference between preventing a production stoppage. Understanding a machines change in performance triggers the need to investigate further, the alternative is unknowingly letting the machine run to fail.
Measurement:
- Single or three phase loads
- Voltage, Current and Frequency
- Power including Active Power (VA), Non-active power (var) and Power Factor (PF)
- Total harmonic Distortion (%)
The Monitor includes a mode to log measurements when no connection to the Fluke Connect® Cloud is available. You can transfer Logged data with the Fluke Connect mobile app.
The total number of measurements depends on the selected topology (wiring configurations), like wye, delta, or split phase.
