TEMPERATURE CONTROL OF CAST RESIN AND DRY MV TRANSFORMERS
Electronic microcontroller based unit, specifically designed to control transformers with more than three windings, such as those used in the conversion DC/AC plants/systems; the NT539 can also be used to control the temperature of distribution MV/LV systems with three phases transformers.
It is equipped with 9 Pt100 inputs and the following relays: 3 for the ALARM, 3 for the TRIP and 3 for the FAN cooling system.
Furthermore, there’s another FAULT relay in common with the whole system, to signal a sensor fault or any other problem inside of the unit.
All our units can also be supplied with a special coating on the electronic cards, resistant to difficult weather conditions, particularly characterized by high temperature and humidity (which are in tropical climates).
UNIVERSAL POWER SUPPLY: with input from 24 to 240 Vac-dc
