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.
In part 2 of our blog series on field service reports we will cover capacitors, what they do, and what to look for. The capacitor in a UPS is used to store an electric charge, as well as smoothing out and filtering voltage fluctuations. UPS systems vary significantly in design and technology, and as a result, the quantity and size of capacitors changes as well. In addition, because a capacitor replacement typically requires a shutdown of the UPS system for replacement, your UPS service provider likely will recommend and replace the cooling fans in the system at the same time. Both capacitors and fans are critical to keeping the UPS running, and both are just as susceptible to failure as the other components of a UPS. It is critical to understand how each component can be damaged, and what to look for in your field service report (FSR) regarding the health of your capacitors and fans.

We previously discussed what you should look for when reviewing a proper service contract for emergency back-up power systems maintenance. When you hire a qualified firm to perform maintenance inspections on your equipment, you need to have total confidence in that firm’s level of knowledge and level of execution of inspection and testing. But how do you know what is most important to look for when that firm shows up at your office, ready to perform maintenance? We will briefly discuss what you should be looking for, and also what to watch out for with these inspections. Please be aware that this is an abbreviated list and should not be considered comprehensive.
You are feeling good about your negotiations with your new service provider. The discussions about your equipment have been excellent, and your rep really seems to understand your needs. You have a service contract in hand and are ready to sign.
Before you put pen to paper sealing the deal, it is very important to review your service contract carefully before moving ahead. While you think you know what your costs will be for services, you need to beware of potential “hidden costs” that can trip you up and cause headaches in the future. Here are some things to look out for when you are doing that review: Continue reading “The Hidden Costs of Your Service Provider” »
