T119 Protective relay for encapsulated dry-type transformers
Temperature control relay
The T119 is a unit developed to monitor the temperature of MV moulded resin and dry-type transformers. It can be used to monitor the windings of your electrical transformer.
The T119 is a unit developed to control the temperature of MV moulded resin and dry-type transformers. The use of PTC temperature sensors makes it particularly simple and economical.
The 3 PTC sensor inputs refer to the alarm (ALL1), trip (ALL2) and fan (FAN) thresholds.
Each input can be connected to 1 to 9 PTCs in series.
Any sensor or unit anomaly is signalled as a fault alarm.
Universal power supply with 24 to 240 Vac-dc input.
Accessories and options
The T119 thermal protection relay ensures the safety of dry or resin-coated transformers:
- Standard distribution transformer
- Dual voltage transformer
- Traction transformer
- Special dry-type transformers
We offer several PTC probe references for connecting your transformer to the T119.
Use and maintenance
