Feeder Protection Relay F-RLY100L

Overview

The F-RLY100L Feeder Protection Relay is a compact and intelligent protection and control device designed for reliable operation in power distribution systems.The relay provides an optimized composition of protection, control, measurement, and communication functions in one unit, with the best performance and usability in its class.

This newly developed Feeder Protection Relay offers comprehensive protection and control functions for both indoor and outdoor primary equipment. In addition to standard current transformer interfaces, it supports flexible configuration and programmable protection curves compliant with IEC and ANSI standards, enabling precise coordination and enhanced system reliability. Its advanced design ensures fast fault detection, quick response, and improved power quality, providing utilities and industries with intelligent, user-friendly automation solutions for modern digital distribution networks.

Feature and Benefit

Multiple Protection

Realize multiple protection functions for overhead lines, support definite time curve, 26 l inverse definite minimum time curves, 24 user-defined curves, comply with IEC and ANSI standards, and satisfied with diverse needs of customers.
Modular Design

With modular design, power supply, control, measurement and communication are realized by independent cards separately, which is conducive to the extension and replacement of cards at customer sites, saving customer's costs and maintenance time.
Waveform Capture

Support record 10 fault records with a maximum of 10 seconds at the storage rate of 128 sampling points in each fundamental frequency period, and store up to 100 fault wave-forms to help customers comprehensively analyze the reason of the fault, tracing the rooting cause to solve the problem.
Power Quality Analysis

Support power quality analysis, you can check the proportion of harmonic components of up to 16 analog quantity in real time, including current, voltage, active power, reactive power, apparent power, and up to 11 harmonics can be calculated to meet Customers’ high-quality electricity demands.
