M‑5625 Digital Synchronizing System
Digital Synchronizing System
When the M-3410A relay is connected with Line-Line voltage input, the following functions are available
(refer to Figure 7 for wiring connections).
• Sync-check with Phase Angle, ∆V and ∆F with dead line/dead bus options (25)
• Reconnect enable (79) for intertie application
• Phase undervoltage (27) detection
• Dual-setpoint, single or three phase, directional power monitoring that can be selected as over
power or under power (32) detection (requires current transformer input)
• Negative sequence overvoltage (47) detection
• Phase overcurrent (51) detection (requires current transformer input)
• Phase overvoltage (59) detection
• VT fuse-loss detection and blocking (60FL)
• Four-step over/under frequency (81) detection
If a line-neutral is applied to the single VT input of the M-3410A only the Synch-Check (25) Function is viable.
The (51) Function may also be active for this voltage configuration if current input is connected as well (refer
to Figures 5 and 6).
Standard Features
• Selectable Anti-Motoring and Anti-Pump
• Adjustable Jog Durations, proportional to error, for Voltage and Speed Controls
• Time Between Jogs adjustments bring the generator to a matched condition in minimum time and
eliminate overshoot and hunting by accounting for inertial and control lags
• Kicker Pulse brings phase angle around through zero if speed is matched but synchronism has
not yet occurred. Adjustable pulse duration compensates for the sensitivity of the governor.
• One Auto-sync output, two Sync-check outputs, one self-test output, two enable inputs, and two
control/status inputs
• Oscillographic recording (COMTRADE file format)
• Time-stamped sequence of events recording for 32 events
• Metering of Voltage, Delta Voltage, Frequency, Delta Frequency, Phase Angle, Current and Sync
Scope indication
• One RS-232 port (COM1) on front and one RS-232 or 485 port (COM2) on rear
• M-3810A IPScom
• MODBUS protocol
• Supports both 50 and 60 Hz applications
• Accepts 1A or 5 A rated CT inputs
• Continuous Self-Diagnostics
Optional Features
