How to Get Faster Three-Phase Power Measurements with Fluke Clamp Meters

Complete three-phase voltage and current measurements 50% faster! We're confident in this because it's been tested at customer sites. The new clamp meters from Fluke (models 377 FC & 378 FC) feature FieldSense™ technology where voltage and current can be measured simultaneously with the clamp jaw. Meaning, these clamp meters can be used to make sequential line-to-ground measurements and current measurements that result in calculated line-to-line voltage measurements and phase rotation information.

In this application note, we walk you through the old versus the new way of doing phase-to-phase measurements along with step-by-step instructions on how to make these measurements.
