Protection Relay 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.
capacitor protection relay Features:
• Multifunction numerical relay
• 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
• Highly flexible programmable relay outputs
• Multifunction external digital input
• Isolated RS485 Modbus -RTU communication
• Selectable 50 Hz / 60 Hz
