The comprehensive protection package of the MRDT4 is specially tailored to protect transformers with two windings.

In addition to the differential protection functions, the MRDT4 also has a wide range of communication and backup functions.

Furthermore, the MRDT4 can also be used as cost-optimized generator differential protection, whereby a block transformer can also be included in the protection zone.

The protection functions of the MRDT4 have been enhanced to meet the requirements of VDE-AR-N-4110/4120:2018.
