The AQ-V251x 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 eleven (11) I/O or communication cards. All this makes AQ-V251x optimal for demanding load shedding and automatic transfer applications that require a large I/O capacity. AQ-V251x voltage protection device communicates using various protocols, including the IEC 61850 substation communication standard.
The AQ-V251x comes in two variants: AQ-V251A has all the I/O capacity and protections, while AQ-V251B also includes the synchronizer control function.
A large I/O capacity.
Eight (8) frequency stages and eight (8) setting groups for load shedding.
Synchrocheck for up to three (3) circuit breakers.
