Relays Offer Power System Protection, Control and Supervision for Distribution Apps

ABB has released three new Relion product solutions for utility distribution and industrial applications.

This includes the Relion 615 series version 2.0 ANSI relays – REF615, REM615 and RET615 – designed to specifically serve North American customer needs in feeder, motor, and transformer distribution applications. These new products are ANSI-qualified and UL Listed.

The Relion 615 series portfolio of distribution protection relays serve basic to moderately complex applications as part of the larger Relion product family of transmission and distribution protection and control IEDs. Common features include ease of use with one programming tool, flexibility of ordering to best fit application, and advanced technologies even in the most basic product feature offerings.

Jeff Vaughan, sales and marketing manager, Distribution Automation, ABB, said, “The 615 series preserves infrastructure investments by supporting legacy protocols, while also complying with the IEC 61850-8-1 standards. IEC 61850 compliance ensures interoperability between present and future substation automation devices, and also saves money by reducing wiring material and labor.”

All Relion relays are equipped with an ethernet port and embedded web server that allow for ease of access and data retrieval by field technicians using a readily available ethernet cable and web browser interface. This reduces the potential for losing critical time locating unique software and adapter cables that have traditionally been commonplace. The compact and withdrawable design further allows for quicker installation, maintenance and testing, and allows for cases to be installed and wired before delivery of the plug-in units. The 615 series can also be equipped with arc flash detection for increased personnel and equipment protection.
