Product Overview
The 1MRK002247-AGr00 is a plug-in analog transformer input board developed for ABB Relion 670 series protection and control IEDs. It acquires secondary current and voltage signals from current transformers and potential transformers, converting analog power system waveforms into digital data for protection algorithms, fault detection and power measurement. This hardware delivers high-precision signal sampling essential for differential protection, distance protection and metering functions within substation relay systems. Protection engineers, substation technicians and automation integrators deploy this module for new switchgear build projects and legacy IED spare replacement. Onboard signal filtering suppresses electrical noise induced by switching transients in high-voltage substation environments.
Application Scenarios
- HV/MV Busbar Protection IEDs: Supplies three-phase voltage and multi-circuit current measurements for busbar differential protection schemes. Reliable signal acquisition enables rapid identification of internal bus faults.
- Power Transformer Protection Panels: Captures primary and secondary winding CT/PT signals, supporting differential protection, overexcitation supervision and load monitoring functions.
- Generator Protection Systems: Processes generator terminal voltage and current signals for stator fault protection, power factor monitoring and synchronisation supervision.
- Wind & Solar Farm Substation Control Cabinets: Works with feeder protection IEDs to monitor grid voltage, current and power flow at renewable energy interconnection points.
