ABB SYN5202A synchronization relay

ABB SYN5202A

The ABB SYN5202A is a synchronization relay used for synchronizing generators, busbars, or other power system elements before connecting them to the grid. Below are its typical technical parameters:

General Specifications:

• Supply Voltage:
  • Rated Voltage (Uₙ): 48–250 V AC/DC (depending on model)
  • Frequency: 50/60 Hz

Synchronization Parameters:

• Voltage Difference Setting (ΔU):
  • Adjustable range: Typically 1–20% of nominal voltage
• Frequency Difference Setting (Δf):
  • Adjustable range: Typically 0.01–1.0 Hz
• Phase Angle Difference (ΔΦ):
  • Adjustable range: Typically 1–30°
• Slip Frequency (for generator synchronization):
  • Adjustable range: 0.01–1.0 Hz

Timing Characteristics:

• Closing Command Time:
  • Adjustable (typically 10–500 ms) to compensate for breaker closing time
• Synchronization Window:
  • Adjustable for early or late synchronization

Inputs & Outputs:

• Binary Inputs:
  • For control signals (e.g., start sync, enable)
• Relay Outputs:
  • Trip/Close signals for circuit breakers
  • Alarm signals (sync failure, voltage/frequency deviation)

Communication & Interfaces:

• Optional Communication Protocols:
  • Modbus RTU, IEC 61850 (depending on model)
• LED Indicators:
  • For status (sync in progress, sync successful, fault)

Environmental Conditions:

• Operating Temperature: -25°C to +55°C
• Storage Temperature: -40°C to +85°C
• Humidity: Up to 95% RH (non-condensing)

Standards & Certifications:

• Compliance: IEC 60255, IEEE C37.90
• EMC Immunity: IEC 61000-4 (for industrial environments)

Typical Applications:

• Generator synchronization
• Busbar synchronization
• Grid reconnection after islanding
