This 100kva dry-type transformer will be sent to South Africa. High voltage 400V, low voltage 190V. The transformer is equipped with a PT100 sensor for each phase and temperature controller. The windings are made of Class H insulation material.
Thermostat working principle:
1. Built-in three-phase winding PT100 probe, detects winding temperature in real time, and displays the temperature cyclically on the digital screen.
2. Circuit break alarm and fault self-checking
Alarm display and output
3. Stage action:
A. When the temperature reaches the set value, the first-stage cooling fan starts automatically;
B. Second stage high temperature alarm
C. The third level over-temperature trip.
4. Fan manual/automatic control switch
5. Fan scheduled start/stop
6. Historical data recording and output
7. 4-20mA current output (optional)
8. RS485 Modbus communication protocol (optional)
9. Ambient temperature measurement function (optional)
