Understanding Field Service Reports Part 4: Thermal Image Scanning

/2 Comments/in , , , , /by

Our fourth and final entry in our series on understanding field service reports looks at deciphering the results of thermal image scanning. The thermal image scan is important enough that QPS believes that every preventative maintenance check should have one performed. Thermal image scanning is one of the most reliable ways to predict impending UPS component failure, and if components, or the entire UPS, needs to be replaced.

Understanding Field Service Reports Part 3: Balancing UPS Loads

/1 Comment/in , , , /by

Our third entry in our series on field service reports concentrates on understanding balancing UPS loads. Before we dive in, let’s start by defining what it means to balance UPS loads. The definition of balancing UPS loads means to distribute loads evenly across the total output of the UPS.

Balancing UPS loads is normally recommended in order to avoid overuse on any one phase of the UPS equipment. In an example with a 3-phase UPS, the UPS puts out a certain amount of amperage, which can be separated into thirds of the total kVA rating across the three phases. When properly executed, balancing UPS loads avoids overuse and increases the useful life of the UPS by maximizing its output.

We are all familiar with going to the doctor to get a check up on our health.  At the end of our visit, we typically receive a summary of what the doctor discussed with us, any tests they did, and recommendations they have for us related to those test results. A field service report (FSR) for your UPS system maintenance is similar to a health check for the unit, giving information on the condition and reliability of the UPS. Most UPS field service reports should include the unit information and location, a job description of what is being inspected, what actions were performed and their results, and the recommendations as the result of the job. In the coming weeks, we will break down a UPS service report and cover some of the main items that you should look for.
