DESCRIPTION

The Temperature Relay TR-42 has been designed for continuous monitoring of the temperature, the cooling fan's control and overheat protection for resin or air insulated three-phase transformers.
 
Thermal detectors PT100 DIN 43760, three of them located inside the transformer coils and the fourth at the core, detect the temperature.
 
The TR-42 relay is microprocessor-based equipment designed to satisfy all control requirements and guarantee high reliability.
 
The TR-42 perform the following functions:
 
Measurement:
 
-Coils and core transformer temperatures, automatically each 5 sec or manually.
-Highest temperature indication and storage.
 
Signaling and programming:
 
-7 segment display and led indication.
-Simplified programming through frontal push buttons.
-Display and non volatile storage of: alarm temperature, trip temperature, fan on, start and stop fan temperature, highest RTD temperature, baud rate of serial transmission, and assigned relay address.
 
Protection:
 
Programmable setting from 0° to 220°C, with separate output contact for the following protection:
-Alarm temperature.
-Start and stop fan temperature.
-Overheat transformer disconnection.
-Alarm of TR-42 failure or PT100 disconnection.
 
Communication:
 
Remote digital communication to a PC or PLC, via RS422 or RS485, allowing:
-Remote adjustment of protection and relay characteristics.
-Storage of faults and events for further statistical treatment.
-Self-explanatory software that requires no additional programming.
