TOTUS OLTC Monitor

A continuous online transformer monitoring solution for on-load tap changers.

How TOTUS OLTC Helps

On-load tap changers are critical moving components in transformers and they endure constant mechanical and electrical strain. Contact wear, loosening of components and thermal stress can lead to transformer failure, fires and even explosions. The TOTUS OLTC provides continuous online transformer monitoring, delivering the clearest view of OLTC health. By correlating mechanical, electrical, and operational data, it provides early fault warnings, enabling proactive maintenance that helps you avoid unplanned outages, reduce repair costs and extend asset life.

What TOTUS OLTC Delivers

Operational monitoring

Tracks tap changer switching operations, providing a detailed operational history to assess wear and identify abnormal behaviour.

Mechanical condition monitoring

Monitors mechanical movement patterns to detect wear, misalignment or mechanical issues, enabling timely interventions.

Enhanced electrical analysis

Measures key parameters like tap position, motor current and temperature, enabling earlier fault detection and condition-based maintenance.

Torque & temperature monitoring

Tracks OLTC torque during tap changes, comparing data to detect deviations and identify potential thermal stress.
