Case Studies

United States: Financial Data Center in Dallas, TX

A major financial institution partnered with Electricaltestingfordatacenters to deploy a high-redundancy rack power system. After our diagnostics revealed inefficiencies in power distribution and cooling balance, we implemented advanced metered PDUs, redundant feeds, and thermal monitoring systems. The result: a 26% increase in energy efficiency and zero power-related outages over 12 months.

United States: Colocation Facility in Northern Virginia

We were engaged by a Tier III colocation provider seeking to improve rack power density and real-time monitoring. Our custom-configured solution included smart PDUs, sensor calibration, and integration into their DCIM software. Post-deployment, the facility reported reduced operational costs and improved SLA compliance.

Canada: Telecom Hub in Toronto, ON

A leading Canadian telecom provider sought our help in upgrading legacy racks with intelligent power systems. We supplied and tested systems from GAO Tek Inc., including integrated current and temperature sensors. The project achieved measurable uptime improvements and enabled predictive maintenance scheduling.
