Electric utilities face ever-increasing demands to reduce costs and improve reliability. Until now, these goals were mutually exclusive when it came to transformer protection. You could either select a higher-cost transformer switch with advanced protection capabilities, such as a circuit-switcher or circuit breaker, or you could choose a lower-cost device with limited protection capabilities, such as power fuses or a high-speed ground switch.

But now there’s a device that meets both goals. S&C’s Trans-Rupter II Transformer Protector is designed exclusively for primary-side protection applications on distribution substation transformers. It gives you all the features you need for reliable transformer protection, and it eliminates those you don’t. With its simple installation procedure and no periodic maintenance needs, the Trans-Rupter II Transformer Protector not only ensures low installed cost, but low operating costs as well.
