Westinghouse became one of ELSCO’s largest customers and was soon joined by other major transformer manufacturers. Due to the specialized technical knowledge and craft required, there was little competition for this repair work and ELSCO’s business grew rapidly.

From the beginning. ELSCO has been privately owned and operated by five generations of electrical engineers and electricians. Since our inception, transformers have always been our business, and we are dedicated to servicing the needs of our customers.

Our Commitment to Quality

For over 100 years, ELSCO has reverse-engineered, repaired and rebuilt thousands of failed transformers made by other companies. We have seen every reason that a transformer can fail. Decades of hands-on experience convinced us that the #1 reason transformers fail prematurely is inferior quality due to false economies in design, materials and workmanship.

A high-quality transformer provides measurable economic value to its user because it is more energy-efficient, runs cooler and quieter, performs better under transient and overload conditions and has a longer useful life. This pays off in the short term but can substantially lower the total cost of ownership over the life of a transformer — often 25 plus years for a top quality transformer.

As transformer technology progressed over the years, we created new techniques to further improve the quality of the transformers we rebuilt for our customers. This can be attributed to Alvin Broverman, our chief engineer for 25 years, who pioneered the use of computer-aided design and testing of transformers. He was also the architect of the design and testing programs we still utilize today.

We use our proprietary designs and assembly methods to produce premium quality transformers that deliver measurable economic benefits to our customers. The relative cost savings from installing and using an ELSCO transformer can represent a significant return on investment.

Our Commitment to Quick Response

From 1950 to 1980, US industrial power consumption grew eight-fold along with the growth in automated manufacturing and continuous-process industries. By the mid 80’s, the rate of transformer failures significantly increased as generations of older transformers reached the end of their useful life. This created a demand for quick delivery of replacement transformers to restore lost power to time-critical industrial operations.

For many industrial buyers, having to wait several weeks for repairs or rebuilding was not an option; they needed immediate delivery from stock. In 1988 ELSCO began to manufacture and stock a line of high-quality medium-voltage transformers to meet those emergency needs.

Today we maintain a large stock of new ELSCO dry-type transformers in the 500 to 2500 KVA range. These meet or exceed the BIL (Basic Impulse Level) and Department of Energy efficiency standards, with 95% item availability, a 24-hour Quick-Ship capability and a five-year warranty. We also stock liquid-cooled padmount transformers in several KVA ratings for applications where liquid cooling and outdoor use is required.
