Best practices to maintain industrial UPS systems

industrial UPS systems provide a buffer between the equipment or load that uses power and the power lines that feed electricity to the equipment. As earlier articles here establish, UPS systems are critical for businesses as well as services to keep equipment running during power outages and other electrical problems. UPS systems can fail due to factors such as misapplication, abuse, and neglect. Maintaining and servicing UPS units is thus important to prevent that from happening. Keeping that in mind, this article looks at some of the best practices in maintaining and servicing UPS units.

Call upon qualified personnel for maintenance

Given the critical role industrial UPS systems play during electrical problems, maintenance of this system needs to be carried out by a qualified person who has knowledge of the client’s electrical network as well as the UPS system. Improper maintenance could only prevent the actual problem from being found and redressed, or it could lead to total failure of the UPS as soon as the unit is put back into service.

Consider the environment

Different environmental factors can affect efficient functioning of the UPS system. For example, dust might be obstructing air-flow or moisture could end up corroding the connections. Poor wiring could prevent power flowing efficiently from UPS to the equipment. Even if these factors do not seem to be limiting the UPS unit’s ability to function smoothly, they could decrease the life of the unit’s internal components and raise servicing and maintenance costs in the long run.

Perform a load bank test at regular intervals

A load banks system test is performed by simulating a power outage and connecting the UPS to the exact amount of load it is expected to support in real conditions. This test can immediately identify the faults in a UPS system. However, it tends to be costly and time-consuming. Regular inspections and preventive maintenance should thus be the key to keeping the UPS healthy.

Monitor battery health

Batteries are the most important component of how a UPS system works. Even though a battery has an expected lifespan of 5 years, extreme temperatures can affect battery life. Store the batteries and UPS system improper float voltage and repeated cycling use can also lead to early wearing out of a battery. Test advised for better battery maintenance include thermal scans, and voltage testing, coupled with visual inspection.
