Hello All, first time posting to the site.
I am electrical engineering for a design firm that specializes in moveable bridge inspections and design. During our site inspections, we perform voltage and current recordings (typically single phase) of 3-phase induction motors, ranging from .25 to 150HP, fed via across-the-line starters, VFD's, or stepped resistance. We currently use Fluke 289 true RMS meters to measure the current and voltage. Problem with the 289 meters is they are single channel only. So to perform 3-phase current and voltage, you basically need 6 meters (assuming one operation), and then line up the time stamps, which is not 100% accurate. We export the data and analyze the running vs peak amps. I am looking for recommendations for 3-phase logging meters that can measure 3-phase current and 3-phase (channel) current all in one shot and easily export data to excel. The meter needs to be capable of measuring the peak amps and have a small sampling rate. The 1700 series fluke meters, specifically the 1738, appear to be a good fit but seem way overkill for what we would use it for. Any recommendations would be greatly appreciated! Thanks in advance.
