Quick Summary

Eaton transformer relay is a protective device that monitors transformer health in electrical substations and large industrial plants. Many users struggle with integrating protection relays into fiber-based networks, resulting in data gaps and slower fault isolation. Key capabilities such as eight digital inputs, nine outputs, Modbus RTU or DNP3 RTU over fiber, and a wide power range support reliable, scalable protection. Industry certifications should be verified with Eaton, as documented compliance is listed as 'Contact Manufacturer' for this model. This combination of features delivers measurable business value by enabling faster fault diagnosis, reduced downtime, and seamless integration with plant SCADA and energy-management systems.

FAQs

Install with standard protection panel practices: mount the relay in a suitable enclosure, connect eight digital inputs and nine digital outputs to the protected transformer circuit, and wire the power supply within 19-300 Vdc or 40-250 Vac. The removable terminals simplify field wiring, and the Modbus/DNP3 communications enable seamless integration with existing SCADA and protection schemes.
The unit accepts 19-300 Vdc and 40-250 Vac with a 50/60 Hz frequency rating. Communications include Modbus RTU or DNP3 RTU over fiber optic ST, with 2 current sensing inputs and 8 digital inputs plus 9 digital outputs for comprehensive protection and metering functions.
Yes. It supports transformer protection duties including differential protection, power protection and metering, current and voltage protection and metering, and zone selective interlocking (ZSI 2). Its rugged design, fiber communications, and expandable I/O make it well suited for substation transformer protection and fast fault isolation.
Compliance information for this model is listed as 'Contact Manufacturer.' The unit features conformal coated circuit boards for reliability in harsh environments and is designed to integrate with standard protection architectures. For formal certification statements (CE, IP ratings, SIL, etc.), consult Eaton documentation directly.
Maintenance is simplified by removable terminals and a modular design, reducing onsite downtime during servicing. Fiber-based communications improve reliability and MTTR, potentially lowering maintenance costs. Warranty is 1 year from installation or 18 months from shipment, whichever occurs first, offering initial protection against early failures.
