Product Description

Overcurrent relays are used for phase and ground overcurrent protection in utility, industrial and commercial electrical power sys- tems

Product Description

SANDA's SD2200 combined overcurrent and earth-fault relay is a digital microprocessor based relay. This relay employs extensive advance numerical technique simple mented in real-time, for the computation of measured input quantity. Other advance features include programmable control output, metering and fault data recording.

Overcurrent protection Functions:

1 Phase Overcurrent Protection

2 Earth-Fault Protection

3 Low-set Characteristic Curves

4 High-set Characteristic

5 External Binary Input

6 Relay Output

7 Configuration

8 Metering and Fault Record

Overcurrent protection Features:

• Multifunction numerical relay

• Three-phase, low-set and high-set phase overcurrent
• Two sets of low-set and high-set setting for phase overcurrent
• Low-set and high-set earth fault
• Two sets of low-set and high-set setting for earth fault
• Four selectable IDMT characteristic curves
• Definite time for low-set and high-set
• Numeric display of phase and earth fault currents
• Display of relay settings
• 9 non- volatile records of previous tripping currents
• Recording of relay start time
• Highly flexible programmable relay outputs
• Multifunction external digital input
• Isolated RS485 Modbus -RTU communication
• Selectable 50 Hz / 60 Hz

Overcurrent protection Benefits:

  • Programmable relay outputs provide a high degree of flexibility
  • Definite time for low-set and high-set
  • Digital display for ease of use
  • Robust casing protects the unit from external interference
  • Complies with IEC 60255-26 standards

Overcurrent protection Applications:

  • The SD2200 combined overcurrent and earth-fault relay is used where time graded overcurrent and earth fault protection is required.
