Description
Product Introduction
⚡ Product: RET670
🏷️ Part Number: 1MRK002816-AB
🔧 Brand: ABB
🛡️ Product Type: Transformer Protection and Control IED
The ABB RET670 1MRK002816-AB is a Relion 670 Series transformer protection and control IED designed for power transformers, autotransformers, generator-transformer units, phase-shifting transformers, and shunt reactors. The unit combines protection, measurement, monitoring, and control functions in a single intelligent electronic device.
🔍 Its protection functions can include transformer differential protection, restricted earth-fault protection, overcurrent and earth-fault protection, overexcitation, thermal overload, and voltage/frequency protection, depending on the configured application. The device supports digital substation communication and can be engineered using ABB PCM600.
🏭 The RET670 is suited to substations, power generation facilities, transmission networks, and industrial power systems where transformer protection and control are required. The exact hardware configuration should always be checked against the complete ordering code and nameplate before replacement.

Installation & Use
🛠️ Before installation, verify the complete 1MRK002816-AB ordering code, hardware configuration, auxiliary supply, CT/VT ratings, communication interfaces, and existing protection settings.
🔌 Disconnect and isolate the relevant equipment before installation. Check CT and VT wiring carefully and confirm terminal assignments against the approved protection drawings. Incorrect CT wiring or configuration can cause unwanted protection operation.
💻 For commissioning, use the appropriate ABB engineering environment to verify configuration, communication parameters, protection settings, binary inputs, outputs, and event recording.
📊 Perform secondary injection and functional testing of the configured protection functions. Verify differential protection, earth-fault protection, trip outputs, alarms, measurements, and communication with the substation control system before returning the transformer to service.
⚠️ Protection relay settings are application-specific. Do not copy settings from another RET670 installation unless they have been reviewed and approved for the actual transformer and protection scheme.
