Partner with AZZ to Mitigate Emergency Outages and Reduce Losses
When your operations slow or cease for any reason other than a total power outage, it constitutes a full-fledged emergency. Downtime is lost money. When thousands to millions of dollars are at stake, you need a response team that can react quickly to remedy the issue immediately. You simply can’t afford not to.
That’s why AZZ recognizes your emergency as their own. Our capabilities as a bus manufacturer provide our field technicians with a vital advantage over service-only contractors. Our goal is to get your plant back on line as soon as possible.
Consequences of Emergency Outages
Transformer failure can grind operations to a halt, causing a ripple effect throughout a power plant. A downed transformer can be catastrophic with severe consequences that could lead to management dismissals, lawsuits, and angry stockholders. When power generation is no longer viable from a faulty transformer, getting the transformer back online has to be done with haste and with a reliable service partner.
The truth is that responder failures do occur, particularly for older facilities that have been in operation for years. A study from the University of Zagreb found that the average life cycle of a transformer is 40 years. Thus, any plant with transformers hovering around this age should be concerned. Years of heat and moisture infiltration that leads to insulation break down are a common cause for shortages on these older parts. Just one fault can cause an entire plant to go down and result in devastating financial losses. A proactive approach can protect you when—not if—a transformer problem occurs.
To curtail losses, it’s important to have a solutions partner ready to act in the case of emergency transformer replacement. Enclosures that protect this vital equipment typically house other gear that can hinder replacement line-up. Thus, the new transformer must be the same form, fit, and function of the existing equipment to ensure quick recovery. When attention to details can translate to a quick, cost-effective plug-and-play solution rather than a lengthy and costly replacement process, AZZ is the partner to turn to.

AZZ in Action
With more than 50 years of experience, AZZ is uniquely qualified to be there when a transformer emergency occurs. In fact, our breadth of experience, knowledge, and capability helped to resolve an emergency situation at a major power plant in Saudi Arabia.
When an explosion on a critical 864 MVA generator step-up transformer (GSU) damaged a transformer and gas-insulated line that connects the transformer to a 380-kV gas-insulated substation, AZZ dispatched the local Country Manager to the site to assess the situation. Damage photos and instruction book drawings were directed to AZZ’s High Voltage Bus Systems (HVBS) division to create a solution. HVBS then dispatched a Field Services Manager to the site to take detailed equipment measurements to ensure a design that provided the best solution for quick recovery.
Due to the severity of the transformer fault and collateral damage, repairs to 36 sections were required to bring the generator back on line. This presented a huge logistics and manufacturing undertaking, as new components were needed to remedy the problem. Fortunately, AZZ maintains an emergency supply of standard GIL components and boasts the in-house capability to produce additional components. AZZ was able to provide the needed components within days. Air freighted via 747, a total of 22 tons of AZZ high voltage transmission equipment was transported to Saudi Arabia in a 48-hour transit that normally takes 8 weeks from origin to destination.
Typically, an endeavor of this magnitude would take 5-6 months to accomplish. AZZ, however, was able to complete repairs, installations, testing, and more, bringing the plant back to normal operations in less than 39 days, just in time to meet mid-summer peak demand.
