Case Study #148 | The Cost of Deferred Maintenance

Mar 9, 2021 | Case Study

In this Nationwide Power™ Case Study, we show the importance of routine maintenance and its impact on the overall health and life of UPS systems. This case study specifically looks at the Toshiba 1600EP 22kVA UPS.

A new customer reached out to our team after their UPS failed to carry the critical power load. Their Toshiba 1600EP 22kVA UPS system is 9 years old and has not had regular preventive maintenance.

Application Radio Communications
Synopsis The business recently conducted a generator test, which included a load test on their 9-year-old Toshiba 1600EP 22kVA UPS system. When the UPS system was unable to carry the load, the on-site generator technician reported a burnt smell.
Our team was contacted for further inspection.
Preliminary Actions A Critical Power Professional™ (CPP™) was dispatched to the site where the CPP found older batteries installed in the unit, along with inductor failure and lack of capacitor maintenance.
Resolution After in-depth troubleshooting and pricing repair costs, it was determined that the most cost-effective and reliable solution to the customer would be a full system replacement. A full system replacement would come with a one-year manufacturer warranty, newer and more efficient technology, and the option of going with a modular unit for better future scalability and redundancy.
Root Cause Some businesses often choose deferred maintenance as part of cost saving efforts. Unfortunately, this can lead to larger out-of-pocket expenses in the future.
In this scenario, it is reasonable to expect that the customer would have extended the life of their UPS system by at least 5 years with proper maintenance, lowering the overall cost of ownership.
