Loss of grading /discrimination may occur:

If R2 Electromechanical & R1 Inst. reset or if R2 DTL reset and R1 electromechanical

Some compromise may be necessary where more than two relay points are in series

Argus 7 - Key Features

Check and system synchronising relay for 50Hz or 60Hz systems

Independent phase angle (Line and Bus Voltages), slip frequency (Line and Bus Freq) and slip timer settings

Independent undervoltage blocking and differential voltage blocking (Line and Bus)

Split system detection with split timer (90-170 Deg)

Options for dead line and/or dead bus charging (Sync bypass logic)

Integrated manual close guard function

Line & bus voltage trimming



PEEBLES REYROLLE

Argus 7 - Close guard feature Prevents an operator from initiating a manual circuit breaker close before the check synchronising relay operates

Removes the need for additional relays e.g. B66
