Synchronous Motor Relay GMS7002
Protection of synchronous motors with various types of driven loads including centrifugal or reciprocating compressors, crushers, etc. 

There are three models: 
GMS7002: Used when 3 phase voltages are available (3VT/ distributed neutral) and when the zero sequence voltage, calculated internally, is used as a characteristic value in the operation of the relay. 
GMSH7002: Used when 2 phase to phase voltages are available and when zero sequence current is used as a characteristic value in the operation of the relay. 
GMSV7002: Used when 2 phase to phase voltages are available and when zero sequence voltage, from a star point or open-delta VT, is used as a characteristic value in the operation of the relay. 

ANSI functions: 
GMS7002 & GMSV7002: 
49 / 46 / 55 / 50 / 51LR / 59 / 24 / 27 / 81 / 32P / 59G 
ANSI functions for GMSH7002: 
49 / 46 / 55 / 50 / 51LR / 59 / 24 / 27 / 81 / 32P / 64
