Transformer Relays
Transformer Relays provide primary protection, control, and back-up protection of transformers, including current differential, restricted ground differential, and overcurrent protection.
DP-300
By selecting the vector group in the display, users can change the phase shift of the transformer without having to worry about changing the connection of the external current transformers (CTs).
ETR-4000
Eaton’s ETR-4000 transformer protection relay has been designed for maximum user flexibility and simplicity. Multiple current inputs provide primary protection, control and back-up protection of transformers.
