High-impedance differential relay
7VH60 Siemens Energy

The SIPROTEC 7VH60 relay is designed for fast and selective differential protection based on the high-impedance circulating current principle. It is used for the protection of machine stator windings, busbars and transformer and reactor windings against phase-to-phase and phase-to-earth short-circuits.
As an option, the relay includes a bus-wire supervision and the differential function can be blocked by a binary input.
