Transformer Differential Relay DTT7031
Biased three-phase differential relay designed to protect high voltage transformers against internal faults.
To operate correctly, the DTT7031 must be installed with a special CEE interposing current transformer (rated at 1A or 5A) to account for the phase shift introduced between the primary and secondary windings of the high voltage transformer.
ANSI function: 87T
See the homepage for Static relays for the full brochure.
