Transformer protector
By Staff -- Consulting-Specifying Engineer, 10/1/2000
Transformer protector is designed exclusively for primary-side applications on distribution substation transformers rated up to 60 MVA at138 kV. Electrically linked, manually reset pole-units provide less than 1/4-cycle, three-phase tripping simultaneity. The device is compatible with any relay-tripping system. It features hermetically sealed interrupters that eliminate the hassle of field filling with SF6 and provide 31.5-kA fault-interrupting performance. (S & C Electric Company) Circle 15
