The device is suitable for piecewise configuration protection of generator side ground fault. 100% stator and rotor ground fault protection with REG216/316*4 requires injection unit REX010 and injection transformer REX011. The injection equipment is suitable for grounding and excitation systems of all ordinary generators.
This protection is effective in all states of the machine, at rest, as well as start-up and running states.

• Compact design
• Perfect match with REG216/ REG316*4
• Provides protection of the entire stator winding, including neutral points
• Continuous monitoring of injection voltage and primary grounding system
• Applies to two separate ground points within the protected area
• Continuous self-monitoring of the amplitude and frequency of the injected signal
• Auxiliary DC power from station battery from 36 to 312 volts DC
• Suitable for all common generator grounding and excitation systems
• Continuously monitor insulation resistance and calculate ground fault resistance
• The principle is based on the well-known offset method, using injected low-frequency signals
• Suitable for updating existing plants
• Insensitive to outside interference
