Communication and interoperability enable seamless integration with IEC 61850, M-Bus TCP, and DNP3 over Ethernet RJ45, supporting unified SCADA interfacing and reduced field wiring. This translates to faster deployment, lower engineering risk, and easier commissioning for transformer protection networks in substations and industrial facilities. Wide power supply compatibility (19-300 Vdc and 40-250 Vac) and 50/60 Hz operation streamline installation across diverse plant environments, lowering inventory needs and speeding up changeovers during grid upgrades. A robust I/O footprint—8 digital inputs, 9 outputs, plus 2 current sensing inputs with removable terminals and projection mounting—gives flexible protection logic and straightforward wiring, reducing commissioning time and error. Sensing capabilities cover Differential Protection, Current Protection, and Metering, enabling precise fault detection and energy monitoring for improved reliability and protection coordination. Zone selective interlocking (2) and optional I/O features (IRIG-B, Trip Coil Monitor, URTD Interface, Sensitive Ground Input) enhance coordination and fault localization, supporting scalable protection schemes as plants grow and regulatory demands tighten. The combined protection and communication suite minimizes downtime, simplifies maintenance, and supports long-term total cost of ownership improvements for transformer protection applications.
