The OTI is designed to monitor the temperature of the transformer oil. It measures the oil temperature and provides an indication of the oil's current temperature.

The OTI is crucial for protecting the transformer against overloads. High oil temperature can indicate excessive loading, and the monitoring system can trigger alarms or protective actions to prevent damage and overloading.

Continuous monitoring of the oil temperature helps prevent thermal stress on the transformer. High temperatures can degrade the oil's insulation properties and lead to premature aging of the transformer.

Rapid increases in oil temperature can indicate internal faults or abnormalities within the transformer. Early detection allows operators to take corrective actions before the situation worsens.

The OTI data assists in load management and helps utilities optimize the transformer's usage and prevent excessive stress during peak demand periods.

The WTI is responsible for monitoring the temperature of the transformer windings. It measures the temperature of the windings and provides real-time temperature indication.

TThe WTI plays a critical role in protecting the transformer's windings from thermal damage. Excessive temperatures can cause insulation breakdown and lead to winding failure.

Monitoring the winding temperature helps operators manage the transformer's load. It ensures that the transformer operates within safe temperature limits, avoiding overheating and potential damage.

Abnormal temperature rises in the winding can indicate issues such as insulation degradation, loose connections, or overloading. Timely detection allows for preventive maintenance and minimizes the risk of transformer failure.
