DV928 / DV966 — neutral mode monitoring and automation units for MV networks (arc-suppression coils)
DV928 and DV966 are neutral mode monitoring and automation units for HV/MV primary substations. They are designed for networks with an isolated or compensated neutral and work with arc-suppression coils.
- DV928
- arc-suppression efficiency evaluation (Petersen coil, shunt), monitoring of MV circuit breaker tripping time
- DV966
- neutral control automation (GSN), undervoltage protection
- Network
- isolated or compensated neutral
- Setup
- via Ethernet

Description
The units monitor systems that compensate capacitive earth-fault currents and control the arc-suppression coil connection circuit. The DV928 evaluates arc-suppression efficiency with a Petersen coil and a shunt and monitors the tripping time of MV circuit breakers. The DV966 performs neutral control automation (GSN) and undervoltage protection. Both units are configured over Ethernet.
