How long does the logging take?

A standard 7-day continuous log captures a full weekly operating cycle including shift changes and weekend loads â long enough to catch intermittent issues a snapshot reading misses.

What does IEEE 519 actually limit?

Total harmonic distortion (THD) on voltage and current, with limits that scale by your point of common coupling's short-circuit ratio. LPES compares your measured THD against the applicable limit for your connection.

Can this study explain equipment failures we've already had?

Often yes â recurring capacitor bank failures, transformer overheating, and VFD faults frequently show a power-quality signature in the logged data that a one-time reading would miss.

Power Quality Analysis — Harmonics, Sags & Swells

Nuisance trips, overheating transformers, and failing capacitor banks often trace back to power quality, not equipment failure. LPES logs your system for 7 days against IEEE 519 harmonic limits and identifies the actual cause.
