Temperature monitoring units for dry-type transformer
Dry-type transformers are used in environments where it is necessary to minimize any risk of fire or power collapse, like in hospitals, data centers, large office buildings, shopping malls, oil & gas production facilities, and even ships.
To secure the reliable and safe service condition of these transformers, different types of bushings and accessories are required.
Our temperature monitoring units type DTI enable controlling alarms and cooling systems, and continuously monitor any anomalous variation in the temperature in your dry-type transformer through PT100 temperature sensors and can detect up to a maximum of four temperatures simultaneously. The monitoring unit DTI protects your transformer from any unexpected failure and costly downtime.
Our temperature monitoring units type DTI are designed for continuous monitoring of the temperature in your dry-type transformer through PT100 temperature sensors
The monitoring unit can detect up to a maximum of four temperatures simultaneously. Each temperature channel has two programmable signaling levels (Alarm – Trip). The integrated diagnostics allows monitoring the status of the PT100 probes (Short circuit – Open circuit) and is possible to signal sudden/abnormal temperature changes (if the FDC mode is active). The monitoring unit can control the start and stop of the ventilation/cooling system. Generally, the temperatures of the three-column windings and that of the magnetic core in the dry transformers are analyzed.
