AQ-R215 Railway Protection Device
Home Protection relays Railway protection AQ-R215 Railway Protection Device
Description
AQ-R215 is a three-phase feeder protection device that can be run either in Standard feeder mode or in Railway mode. In the Railway mode the device provides a single-phase overcurrent, earth fault, and voltage protection. Each protection stage can be independently set to the frequency of 16 2/3 Hz or of 50/60 Hz. When in the Standard mode the functionality of AQ-R215 is identical to that of AQ-F215 Feeder Protection Device. In this mode the relay can also be dynamically set to run on a frequency between 6 and 75 Hz.
You can add up to three (3) I/O or communication cards into the device for more demanding control, alarm and indication needs. AQ-R215 communicates using various protocols, including communication according to the IEC 61850 standard.
Highlights:
Single-phase protection for any frequency range between 6 and 75 Hz.
Double busbar control.
Directional overcurrent and voltage protection.
Low-impedance restricted earth fault protection.
Harmonics protection and control.
5-shot scheme-controlled auto-recloser.
