ABB RET670 1MRK002816-AG comes with high-precision analogue current and voltage input channels, specially built for direct connection with standard current transformers (CT) and voltage transformers (VT) in power substations.

This transformer protection relay supports selectable nominal analogue current inputs of 1 A or 5 A to fit various on-site CT configurations. With a wide dynamic measurement range, the RET670 1MRK002816-AG accurately detects regular load currents and severe fault currents. Low burden consumption on CT loops helps lower transformer saturation risks and stabilises measurement accuracy during power system faults.

The nominal analogue voltage input is 110 V AC, fully compatible with common secondary outputs of substation voltage transformers. These voltage input channels ensure steady signal sampling for voltage supervision, frequency monitoring, synchrocheck and multiple voltage-dependent protection functions.

All analogue current and voltage inputs adopt galvanic isolation structure to resist strong electromagnetic interference in tough substation working conditions. Equipped with advanced internal signal processing, this ABB RET670 relay provides reliable phasor measurements required for transformer differential protection, restricted earth fault protection, overcurrent protection and relevant supervision logics.

Moreover, the auxiliary power supply supports a wide voltage range including 24–250 V DC and 48–250 V AC. Such flexible power input makes the RET670 1MRK002816-AG suitable for wide application scenarios such as power plants, transmission substations and distribution substations.

Pre-commissioning Inspection & Wiring Verification

Inspect the mechanical installation, cabinet earthing and terminal tightening status of the ABB RET670 1MRK002816-AG. Inspect all wiring circuits, including CT secondary loops, VT secondary loops, binary inputs, binary outputs, auxiliary power supply and communication cables. Complete insulation resistance tests on external wiring to rule out short-circuit and open-circuit hazards. Confirm that the selected CT rated current (1 A / 5 A) and VT rated voltage (110 V AC) are consistent with the hardware configuration of the IED.

IED Power-on and Initial Hardware Check

Supply auxiliary power (24–250 V DC / 48–250 V AC) to energize the RET670 1MRK002816-AG. Monitor LED indicators and the startup process of the local HMI. Check the operating status of hardware modules and ensure no internal fault alarms exist. Establish communication with the relay by connecting the PCM600 engineering tool via Ethernet or service port.

Configuration Upload & Parameter Verification

Upload pre-configured project files to the ABB RET670 1MRK002816-AG using PCM600. Verify key parameters carefully, such as transformer winding vector group, CT/VT transformation ratios, differential protection bias parameters, restricted earth fault settings, as well as thresholds for overcurrent, voltage and frequency protection. Enable necessary protection functions and deactivate unused logic schemes. Configure IEC 61850 communication parameters, GOOSE control blocks, event logging and disturbance recording functions. Save all configurations and restart the IED to validate parameter effectiveness.

Analog Channel Calibration & Measurement Test

Connect a secondary injection test set to the analog current and voltage terminals of the RET670 1MRK002816-AG. Inject three-phase rated currents and voltages, then compare the phasor readings displayed on HMI and PCM600 against theoretical input values. Verify the accuracy of phase sequence, amplitude and phase angle. Ensure galvanic isolation operates normally without unexpected signal distortion.

Binary Input / Binary Output Test

Simulate binary input signals via the forcing function on PCM600 or local LHMI. Check status feedback on the relay and the substation SCADA system. Actuate binary output contacts and verify the continuity of trip circuits, alarm circuits and interlock circuits. Confirm all contact signals comply with the designed bay control logic.

Protection Function Secondary Injection Testing

Simulate various power system faults to complete functional verification:

• Transformer differential protection (87T)

• Restricted earth fault protection (REF)

• Phase and earth overcurrent protection

• Under/over voltage protection, under/over frequency protection

Inject fault signals to record pickup values, reset thresholds and operating time delays. Verify blocking conditions, restraint characteristics and fault phase selection logic. Perform synchrocheck testing in accordance with on-site synchronization requirements.

Communication & IEC 61850 Verification

Test the transmission and reception of GOOSE messages between the RET670 1MRK002816-AG and other bay-level IEDs. Validate data exchange with substation SCADA through the MMS protocol. Check the uploading of events, fault alarms and disturbance recorder files. Guarantee accurate transmission of telemetry data, protection status indications and control commands.

Disturbance Recording & Event Log Check

Trigger simulated faults and verify that the RET670 1MRK002816-AG can automatically capture fault waveforms, event sequences and timestamp data. Retrieve disturbance record files via PCM600 to ensure intact waveform data for post-fault analysis.

Overall Logic & Interlock Test

Carry out comprehensive bay logic tests covering transformer control interlocks, breaker operation sequences, protection trip interlocks and blocking logics. Resolve parameter conflicts and eliminate risks of unintended equipment operation.

Final Commissioning & Handover

Remove all test forcing signals, clear fault records and switch the ABB RET670 1MRK002816-AG into operational mode. Recheck all parameters and alarm status. Sort out test records, complete commissioning documents and restore all field wiring to normal operating conditions.
