Electrical Problems. Proven Solutions. No Guesswork.
Picture this: You install precision VFDs and servo-controlled motors. Performance improves, but then the nuisance trips start:
Undervoltage alarms
Communication errors
Random shutdowns
Intermittent faults with no clear pattern
RMS readings at the panel look normal, but modern drives are far more sensitive than legacy equipment. Small sags, harmonics, imbalance, fast transients, or sub-cycle events can trigger shutdowns long before average voltage appears abnormal.
The result: unplanned downtime, unnecessary part swaps, rising costs...and the root cause STILL isn’t confirmed.
WHAT TO DO?
When voltage quality is the suspect, a temporary portable analyzer lets you monitor incoming power under real operating load without shutting down production or permanently installing equipment.
But which perspective do you need?
Waveform detail or long-term voltage behaviour?
