Battery Installation & Testing

Batteries are critical to the operation of your UPS system, poorly installed/maintained batteries can render your UPS unable to take the critical load when called upon.
Regular Battery maintenance is recommended to ensure your system will operate in an emergency.
We use FLUKE 500 series battery testers and provide a comprehensive report on the true condition of each battery cell, monitored over time we can identify problem cells before they degrade the capacity of the entire string.

Full battery testing requires the UPS to be placed into bypass.

Thermographic Survey

A thermographic survey refers to the non-destructive testing of parts, materials, or systems through the imaging of the thermal patterns at the object's surface.

When used as part of your business preventative maintenance cycle, we can identify hot spots within your Buildings electrical system before they become a problem, often rectifying the problem at the time of the survey. We provide a comprehensive report including images of all tested equipment and suggested corrective action if required.
