Case Study: a senior care facility in the southwestern U.S. resolves elevator entrapments with Electro Industries/GaugeTech Power Quality Analysis

a senior care facility in the southwestern U.S. resolves elevator entrapments lasting 1.5 hours with Electro Industries/GaugeTech

A senior care facility in the southwestern U.S. was experiencing frequent and dangerous elevator interruptions that trapped elderly residents for over an hour per event. Electro Industries/GaugeTech was engaged to investigate the issue using their EnergyReporterPQA/EnergyPQA power quality analysis services and Nexus 1500+ power quality meters to identify the root cause of the nuisance safety shutdowns.

Electro Industries/GaugeTech deployed a power quality monitoring system that pinpointed the cause as recurring voltage sags and swells originating from the utility supply. This data-driven evidence allowed the facility to present the findings to their utility provider for a permanent grid-side fix. In the interim, the facility is installing a constant voltage transformer to protect the elevator controls, effectively eliminating the shutdowns and ensuring resident safety.
