TOTUS OLTC Monitor

TOTUS OLTC Monitor

Transformer OLTCs endure constant mechanical and electrical stress. Online monitoring provides visibility of deterioration, helping prevent misoperation and costly failures.

Product overview

The TOTUS OLTC, part of the TOTUS monitoring suite, provides continuous online monitoring for on-load tap changers, a critical, mechanically moving component on a transformer. By correlating mechanical, electrical, and operational data, it delivers the clearest view of OLTC health. By delivering early fault warnings, it enables proactive maintenance to avoid unplanned outages, reduce repair costs, and extend asset life.

Key features

Operational monitoring

Tracks tap changer switching operations, including position, timing, and number of 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 to prevent costly failures and extends tap changer life.

Enhanced electrical analysis

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

Torque & temperature monitoring

Tracks OLTC torque during tap changes, comparing data trending to detect deviations. Temperature monitoring compares expected versus measured OLTC temperatures to identify potential thermal stress.

Benefits of TOTUS

1

Reduced risk

Detect mechanical and electrical faults early to prevent tap changer failures, avoiding costly asset damage, unplanned downtime, and operational disruptions while extending transformer life.

2

Optimised resources

Prioritise maintenance on the assets that need it most, focusing expert resources where risk is highest instead of following fixed schedules.

3

Lower costs

Avoid costly emergency repairs and premature asset replacements by using condition-driven maintenance to act before problems escalate.

4

Extend transformer life

Utilise continuous health monitoring to prevent irreversible damage, maximise asset lifespan, and defer costly long lead time replacements.
