Feeder Protection & Management Relays
The F-PRO family of numerical multifunction relays provide complete feeder protection with a wide range of protection functions suitable for transmission, distribution and industrial applications. This broad selection of relay functionality and hardware options allow customers to choose the best suited and most cost-effective solution for each application. High reliability comes from robust and field-proven design, as well as self-monitoring hardware and a software watchdog.
The F-PRO relays include metering, sequence of event (SOE) reporting with 1 ms time stamp resolution, high quality oscillography waveform capture and fault log facility for analysis. The intuitive and simple Windows-based Relay Control Panel software allows easy configuration and disturbance analysis. Communication options supporting serial and Ethernet interfaces, as well as multiple protocols, allow simplified system integration with substation control and SCADA systems.

The F-PRO is the first line of defense along the power delivery route. When electricity travels from a substation to homes, businesses, or industrial facilities through power feeders, the F-PRO continuously monitors current, voltage, and frequency to detect faults or abnormal conditions instantly. If something goes wrong — an overload, a short circuit, or a voltage spike — the F-PRO isolates the problem in milliseconds, preventing damage from spreading across the network. Its flexible hardware options and intuitive software make it suitable for a wide variety of power automation applications, from simple distribution feeders to complex industrial systems.
IDEAL FOR Utilities managing distribution networks, industrial facilities with complex feeder systems, and engineers who need a reliable multi-function relay with modern digital communications and easy-to-use software.
