Reliable and Versatile Power System Protection
Ensure consistent, high-speed protection with SEL-700 series relays.
The SEL-700 series offers comprehensive protection and control for both utility and industrial power systems. The SEL-700G Generator Protection Relay, SEL-710-5 Motor Protection Relay, SEL-700BT Motor Bus Transfer Relay, SEL-751 Feeder Protection Relay, and SEL-787-2/-3/-4 Transformer Protection Relay are all equipped with innovative features and a common platform architecture to help you streamline processes and standardize protection.
Intuitive Touchscreen Interface
Each relay in the series offers a color touchscreen option with an intuitive interface based on proven design principles. Simple to learn and navigate, the touchscreen interface allows faster commissioning and easier operation. Meanwhile, the large display provides convenient, immediate feedback about your system—view data directly from the relay, without connecting a laptop.
Advanced Communications Capabilities
The SEL-700 series supports numerous communications protocols, including EtherNet/IP and the software-based IEEE 1588 Precision Time Protocol—giving you flexibility to integrate your relays with a wide variety of control systems and devices. The series also features an integrated web server, which provides secure remote access for you to update firmware, view data, and monitor the status of multiple relays simultaneously.
Streamlined Testing and Commissioning
The SEL-700 series features five IEC 61850 standard operating modes, including one for in-service testing. This mode allows you to test your system components in energized substations without the risk of a misoperation—which further simplifies the process and reduces commissioning time.
Durable and Versatile Hardware
SEL-700 series relays are designed and tested to withstand harsh environments and extreme conditions. In addition, the relays support a variety of adapters and retrofit mounting options, making installation faster and simpler for any application, regardless of previously installed equipment.
