V211

Description

The AQ-V211 voltage protection device offers a modular voltage protection solution for substations. The relay includes both voltage and frequency protections as well as powerful logic programming, and you can add up to five (5) I/O or communication cards. All this makes AQ-V211 optimal for demanding load shedding and automatic transfer applications. AQ-V211 communicates using various protocols, including the IEC 61850 substation communication standard.

The AQ-V211 voltage protection device comes in two variants: the “A” variant (AQ-V211A) includes the standard functionalities for voltage protection, while the “B” variant (AQ-V211B) also includes the synchronizer function.

Highlights:

  • Eight (8) frequency stages and eight (8) setting groups for load shedding.
  • Synchrocheck for up to three (3) circuit breakers.
  • Optional synchronizer function.
  • Anti-islanding protection.
