<div>Hello folks,</div>
<div><br>
</div>
<div>We have a problem with a large compressor in a building that keeps shutting down at almost the same time on weekends. I feel like the problem may be some regular anomaly with the three phase power feeding it.</div>
<div><br>
</div>
<div>Can somebody recommend a simple product or method to record the power characteristics so we can go back and review the recorded data to see what, if anything, is going on? We have NMR's and other instruments that record when the compressed air is lost.
It would be very helpful to then review recorded sine wave or other useful information to determine if we have a power problem or if the issue is actually something else. </div>
<div><br>
</div>
<div>It really feels like a regular voltage loss that only happens on Saturday afternoons when not much is going on in the building. This is causing a lot of problems.</div>
<div><br>
</div>
<div>Appreciate any help with this.</div>
<div><br>
</div>
<div>-Michael.</div>
