How to use wireless tools to determine current unbalance
Measurement tools linked by a wireless interface are engineered to make jobs faster, safer and more efficient.
Here’s an example: A technician, equipped with Fluke Connect™ wireless tools, is assigned to test for three-phase unbalance in a motor power cabinet. Here are the steps the tech will take:
- Suit up in personal protective equipment (PPE).
- Open the panel enclosures.
- Attach individual current-measuring device (in this case, the Fluke a3001 FC Wireless iFlex® ac Current Modules) to all three legs, or lines of incoming current, of the motor.
- Close the panels; remove PPE.
- Remotely monitor the readings collected by the modules via a wireless digital multimeter, a phone equipped with the Fluke Connect™ app, or a laptop with wireless adapter and the Fluke Connect™ app.
- No need to reopen and reclose the panels to check readings.
- Reduced risk of arc flashes, since panels do not need to repeatedly opened and closed. Taking measurements when the panel door is closed provides a big safety boost.
- No need to repeatedly put on and take off PPE.
- Access to on-demand measurement readouts for the duration of the test, whether it is scheduled for a few minutes, a few hours or a few days.
- Monitoring multiple measurements at once helps you isolate the current imbalance faster.
- Logging saves you time—you can identify load balancing issues without being physically present.
