UTXvRNT - OLTC Transformer Voltage Regulator
1. General Information
UTXvRNT is a device with very expanded regulation, recording and remote control functions, destinated for the use in on-load tap changer regulation systems on any high and medium voltage power line.
It can be operated with solidly earthed, compensated or isolated neutral point configurations and
provides fast and reliable regulation.
The extended functions include voltage drop compensation, 24-hours / scheduled / weekend and
holiday settings, disturbance and event recording, voltage quality recording. It enables realization of
the most sophisticated applications.
UTXvRNT is available in two versions:
• UTXvRNT2 is designed to control two-windings transformers
• UTXvRNT3 is designed to control three-windings transformers
