Case Study #152 | The Importance of the Critical Power Environment

In this Nationwide Power™ Case Study, we show the importance of a controlled environment and how one can never be over-prepared for the unexpected. This case study specifically looks at the Eaton/Powerware 9330-30kVA UPS.

Product Eaton/Powerware 9330-30kVA UPS
Application Distribution
Synopsis Our Critical Power Professional (CPP™) was onsite for age-based full capacitor and fan replacements. After completing the installation and trying to bring the unit back online, the display had no characters, and the unit would not come back online.
Preliminary Actions After some initial troubleshooting and tracing back from the display, the CPP™ found that a lizard had shorted out the power supply and damaged the display board.
Resolution The CPP™ ordered a replacement power supply and display boards for next-day delivery. After replacing both boards, the CPP™ was able to bring the unit back online. With a full-service contract to stand behind, the customer was able to secure parts and labor for next-day installation.
Root Cause Component failure was caused by an external source, in this case a lizard that was most likely searching for warmth. From time to time, and in different geographic regions, we encounter some unique environmental situations. Some of these can be prevented with strict environment controls, while others can be more challenging. Use best practices to keep your critical electrical equipment safe.

Case Study #151 | The Cost of Deferred Maintenance

In this Nationwide Power™ Case Study, we show the importance of performing preventive maintenance and completing recommendations. This case study is about a Mitsubishi 9900A 150kVA UPS.

After several attempts over the course of many months trying to schedule the first major preventive maintenance inspection (PM), a new customer finally responded by placing an emergency call indicating that there was smoke coming from their uninterruptible power supply (UPS).

Product Mitsubishi 9900A 150kVA UPS
Application Communications/Technology
Synopsis The customer was notified by the original equipment manufacturer (OEM) of an AC capacitor recall, which was covered under warranty at no cost. For over a year, the customer did not respond to the OEM to take corrective action, and as a result the AC capacitors failed. This caused smoke, damage, and forced the UPS into bypass, putting their critical load at risk to downtime.
Preliminary Actions A Critical Power Professional™ (CPP™) was dispatched to the site for the first time since this was a new customer. Upon arrival, the CPP found the UPS against a wall with no rear access and was unable to remove the rear panels for proper inspection. The customer was notified that the UPS requires three feet of rear clearance and the CPP returned two days later, after rear access clearance had been provided.
Resolution After the customer cut the wall open behind the UPS for access, the CPP was able to remove the rear panels where a visual inspection presented damage to 3 of the 4 capacitor assemblies. The CPP then shut the UPS down with the load on maintenance bypass. The OEM was onsite two days later and replaced the recalled capacitors, followed by the CPP performing the major PM.
Root Cause Often, businesses choose to defer maintenance for a variety of reasons. In this case study, a deferred recall preceded a PM that may have identified the failing capacitors and avoided an outage. Additionally, the UPS was installed with no rear access, significantly increasing the time to repair. Fortunately, the section of wall that needed to be removed was not a block or exterior wall.
In this scenario, it is reasonable to expect that the customer would have avoided all the risk for downtime and costs of having a unit on bypass had the recall been performed. Additionally, the failing capacitors and lack of rear access that hindered the repair would have been identified sooner had Nationwide Power been allowed to perform the major PM.

Case Study #150 | The Importance of Prevention

Nationwide Power™ is the leading provider in the critical power supply industry. Our core business is the sales and service of uninterruptible power supplies and UPS batteries, along with supporting other critical power components such as emergency generators, switch gear, and HVAC. We publish critical power related case studies, highlighting best practices and quality standards.

In this case study, we highlight batteries in a Liebert NXb, in which the Critical Power Professional™ found loose battery connections during a routine preventive maintenance (PM) inspection.

Product Liebert NXb UPS
Application Manufacturing Data Center
Synopsis During the first visit with a new customer, a regularly scheduled minor battery PM inspection was performed by the Critical Power Professional (CPP™), who identified three batteries that load tested as weak.
Preliminary Actions

Part of the CPP’s standard procedure for performing preventive battery maintenance is to load test each battery. While batteries may show correct voltages with a standard Fluke meter, placing a battery under load will identify true cell integrity and any degradation weaknesses.

With the CPP measuring battery system voltages, currents, and ohmic values, a final load test of each battery identified three batteries load testing under 60% (56%, 41%, 17% respectively).

Resolution

Upon further inspection of the three weaker load tested batteries, the CPP found that all three batteries had loose battery cable connections, one of which was only finger tight. After torquing to the correct battery hardware specifications, the batteries were load tested again and readings were in acceptable ranges.

Since the customer was under an emergency service contract with Nationwide Power, this preventive maintenance inspection was part of the included coverage and there was no out-of-pocket expense to the customer.

Root Cause The battery connections were improperly torqued by the previous service provider. As a result of routine preventive maintenance inspections, system load loss was avoided. Additionally, loose connections could have caused excessive resistance/heat, leading to a possible “thermal condition” or fire.

Case Study #149 | The Additional Hidden Costs of Choosing the Lowest Price

In this Nationwide Power™ case study, we show the importance of having a qualified Critical Power Professional™ (CPP™) perform maintenance on your critical infrastructure equipment. This case study specifically looks at the Liebert NX 120kVA UPS.

A Nationwide Power CPP was onsite to perform a regularly scheduled preventive maintenance (PM) inspection. During the PM inspection, the CPP noticed that the input voltages were running high, and the output voltages were unbalanced.

Product Liebert NX 120kVA UPS
Application Medical Facility
Synopsis During a regularly scheduled PM inspection, high input and unbalanced output readings were found. To further troubleshoot, the uninterruptible power supply (UPS) was placed into maintenance bypass to observe the voltages. No changes were observed and as the unit was being transferred back out of bypass, a short buzzing sound was heard. The transfer had failed, and the critical load was lost.
The downtime was further extended because the failure cleared a fuse in the maintenance bypass panel. Site electricians were called in to help repair the bypass panel. After several hours, a replacement fuse was found and installed, and the maintenance bypass was operational again.
Preliminary Actions A Critical Power Professional™ (CPP™)initiated troubleshooting and found 3 blown output fuses, 3 failed static switch silicon controlled rectifiers (SCRs), and a possible bad SCR driver board. Parts were ordered and shipped from Nationwide Power’s inventory via next day air. Upon returning to the site to repair, the CPP replaced all the parts that were ordered. Continuing the troubleshoot, the CPP focused on the output capacitor section, based upon the output voltage symptoms. Additionally, the output capacitors were recently replaced by another vendor who was awarded the job based upon lowest price, and therefore seemed like a logical place to start.
Resolution After in-depth troubleshooting and removing UPS covers, the CPP was able to determine that the capacitor pan assembly wiring harness plug was not plugged into the UPS. After plugging the capacitor pan connector into the UPS and returning all other parts that were removed, the UPS was restarted, with customer approval, and placed back online in normal mode.
Root Cause Human error caused by a simple electrical connection not being completed.
Even though Nationwide Power was the service provider contracted to maintain the customer’s critical power infrastructure, a lower price option was selected to replace the UPS capacitors. The quality of service, or lack thereof by the other vendor resulted in the “lowest price” costing an additional $5,000 in repairs. The cost of downtime is not included.
Unfortunately, the lowest price is not always the best price, and true cost of total ownership.

Case Study #148 | The Cost of Deferred Maintenance

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.

Product Toshiba 1600EP 22kVA UPS
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.

Case Study

Case Study #147 | What Could Possibly Go Wrong – Eaton 9330 15kVA

In this Nationwide Power™ case study, we hope to show our customers another example of how a full-service contract will save our customers time, money, and headaches in both  the short term and in the long run. In this case study, we particularly focus in on a 15-year-old Eaton 9330 UPS system.

In 2018, Nationwide Power acquired a customer who purchased new batteries and installation, along with a preventive maintenance contract. Due to budget constraints, they opted for annual maintenance only in place of a full-service contract that would have covered parts, labor, and travel.

Product Eaton 9330 15kVA UPS
Application Local County Support
Synopsis The Eaton 9330 UPS system is located in the basement of the facility and is not often monitored. Upon a random inspection, an on-site team member reported that the unit was in alarm but was not aware of how long the system had been in an alarm status.
Preliminary Actions A Critical Power Professional™ (CPP™) was dispatched to the site. After in-depth troubleshooting, it was identified that the power supply board had failed and required replacement.
Resolution One of the major competitive advantages that Nationwide Power holds is the vast inventory of parts and equipment on-hand, totaling over $10 million in value and covering 57,000 square feet of warehouse space.

Once the customer approved the parts order and repair, the Nationwide Power team was able to expedite the shipment of the parts and installation within just 2 calendar days.

Under a full-service contract with Nationwide Power, the power supply board would have been repaired/replaced the same or next day with no additional expenses. The customer would have also saved over $5,000 over the course of the calendar year.

Root Cause While the power supply board failure may have been inevitable in this situation, the out-of-pocket expense to our customer was not.

Our job as a critical power service provider is to guide our customers in the best way possible. We understand the market, the limitation on available parts inventory – particularly in obsolete UPS models, and the potential compound expense of deferred maintenance.

Our ultimate goal is to provide value to our customers by offering affordable and predictable service plans, where Nationwide Power takes the guesswork out of “what could possibly go wrong?”
