Whether classic, diagnostic-capable or freely configurable: our relay solutions are designed for a wide range of applications – from simple individual
The SEL-751 Feeder Protection Relay is ideal for directional overcurrent, fault location, arc-flash detection, and high-impedance fault detection applications.
Traditionally, protective relays were electromechanical devices that utilized induction disk, coils, contacts, and solenoid elements to determine protective characteristics.
The modular design makes it easy to adapt to changing protection requirements for the lifetime of the device. Continuous access to new incrementally released
The Reyrolle 7SR46 Argus is a dual-powered non-directional overcurrent and earth-fault protection device - with specific CTs. The relay provides both definite-time and inverse-time overcurrent and
The front of the device includes an easy-to-use display and push buttons that can be used to programme the relay and view fault records and
Transformer Protection Application Guide This guide focuses primarily on application of protective relays for the protection of power transformers, with an emphasis on the most prevalent protection schemes
Safety relays from Pepperl+Fuchs are equipped with dual redundant contacts. With this sophisticated "one out of three" (1oo3) architecture, it is sufficient if only one
