Success Stories

Our products have been deployed onto many electrical safety and predictive maintenance applications. Here are just a few examples detailing their success in the field.

GraceSense: Stamping Plant

Learn how one of the world's largest automobile manufacturers avoided losing $0.5M in unplanned downtime by installing the GraceSense Predictive Maintenance System in their Automotive Stamping Plant.

GraceSense: Preventing Breaker Failures

The combined effect of unplanned downtime as a result of a single breaker failure could be in the tune of millions of dollars in some highly critical industry verticals. Find out how the Hot Spot Monitor has proven to prevent this from happening by preventing breaker failures with actionable data.

PESD: Steel Manufacturing Plant

A steel producer in Mississippi found that installing GracePESDs® eliminated the potential for user error when deenergizing a detachable crane magnet that had caused two incidents in the past; one resulting in lost time injury.

PESD: Wastewater Utility

Mounting a Voltage Test Station (VTS) at this wastewater treatment plant reduced a 45-minute, 2-man Lockout/Tagout (LOTO) task down to a 5-minute, 1-man LOTO task. More importantly, when using a VTS the risk of energy exposure was mitigated.

PESD: Window Treatment Plant

With 1.25 million square feet of ground to cover and countless motors and equipment requiring LOTO, this facility found that by adding PESDs, they had gone from spending 200-300 hours down to 50-100 hours per year with the Safe-Test Point solution.
