Machine Differential Relay DTM7033
Three-phase percentage biased differential relay.
Provides a solution for the protection of rotating machines against internal faults (longitudinal differential protection).
Can also be used as a transverse differential protection on machines having two accessible windings in parallel per phase (split windings), ensuring protection against short-circuits between turns on the same winding.
ANSI function code: 87 M
