MGM Transformers has supplied medium-voltage transformers to industrial and commercial facilities across North America since the 1970s. Their cast coil and vacuum pressure impregnated (VPI) units have been staples in manufacturing plants, health care facilities and commercial buildings for decades.
Although MGM transformers have earned a reputation for durability, many units from the 1990s are now reaching the end of their service lives. As system demands increase and efficiency standards evolve, businesses increasingly seek replacements that can deliver improved performance and reliability. ELSCO Transformers offers replacement and retrofit solutions that meet these needs.
Why You Might Need to Replace Your MGM Dry Type Transformer
Most MGM transformers manufactured before 2000 were designed for facilities and equipment of that era. These aging transformers may no longer meet the demands of modern facilities and equipment, leading to various performance issues.
Some of the indicators that your MGM transformer might be at the end of its lifespan include:
- Increasing operational temperatures despite proper ventilation.
- Noticeable deterioration of core laminations or winding insulation.
- Energy efficiency below the current industry standards.
- Difficulties finding compatible replacement parts.
- Loud noises and vibrations.
- Rising maintenance costs and more frequent repairs.
Unlike complete failures that need immediate action, these gradual changes often lead facility managers and business owners to delay replacing the unit. However, continuing to operate an aging MGM transformer can lead to escalating energy costs, reduced reliability and potential safety concerns for your facility.
Using a Retrofit Unit to Replace Your MGM Transformer
In some cases, retrofitting is a practical alternative to standard transformer replacement. Purchasing an in-stock system from MGM or another manufacturer could involve modifications and added expenses, including bus work reconfigurations and adjustments to your enclosure.
ELSCO’s MGM transformer retrofits eliminate these challenges by providing a solution that matches your existing MGM unit’s dimensions and connection points. Our engineers document your current transformer’s specifications while identifying opportunities for performance improvements. The result is a system with modern technology and advanced materials that fits perfectly with your current setup.
