K-factor rated transformers are designed to meet the non-linear load demands caused by computers and other modern electronic equipment. These types of loads can cause severe overheating in distribution transformers designed to meet the needs of a pre-electronic era. The Jefferson line of non-linear transformers provides safe and efficient operation in non-linear load environments.
