Case Studies

U.S. – Cloud Hosting Center in Oregon
A large-scale hosting provider used our insulation resistance testers to monitor the backup UPS cabling in its Tier IV data center. Faults were detected early, allowing preventive action and avoiding a potential outage worth over $100,000.

U.S. – Utility Substation in Ohio
Enviro Test for IT supplied high-voltage testers for an electric utility’s predictive maintenance program. By identifying insulation weaknesses in transformers, they prevented critical failures and improved grid reliability.

Canadian – Telecommunications Hub in British Columbia A major telecom operator in Vancouver deployed our insulation testers as part of a broader infrastructure health assessment. The data collected was uploaded to a cloud analytics system, improving maintenance planning and compliance reporting.
