Tap changers are a vital element in regulating power flow within transformers, containing insulating oil that must be constantly maintained for maximum dielectric strength. The oil can become compromised whenever there are contaminants such as carbon, water, and metallic particles present, leading to costly repair downtime or worse, complete destruction of the transformer.

Allen Filters’s ATF Tap Changer Filter systems offer solid, proven, and exclusive benefits that provide your tap changers extended life, cost-effective operation, and reduced oil changes with increased safety and ease of use. In short, the ATF provides optimal conditions for tap changers.
