Case Studies
Case Study 1 – Facility Maintenance Contractor (Georgia, USA)
An electrical contracting firm used ElectricalTestTek’s RCD testers during a system upgrade in a 25-story commercial office tower. They discovered several underperforming RCDs in HVAC subpanels. Our device's fast fault simulation saved hours in troubleshooting and ensured the project passed final inspection on schedule.
Case Study 2 – Industrial Manufacturer Compliance Checks (Pennsylvania, USA)
A renewable energy operator integrated GAO Tek insulation resistance testers supplied by ElectricalTestTek to evaluate turbine wiring integrity. These tests revealed degradation in older systems and helped plan component replacements, improving overall energy output and reducing emergency repairs.
Case Study 3 – Healthcare Facility Diagnostics (Ontario, Canada)
A leading property management firm adopted our testers for routine inspections of large HVAC systems and backup generators. By integrating regular IR testing, they reported a 30% drop in equipment failure-related downtime across 15 commercial buildings.
