Le new TPL503 SYSTEM (control unit BB211 + sensor TPL503 ) represented innovation 4.0 for the protection of hermetically sealed oil transformers.
The conventional electromechanical control devices are replaced by the electronic sensor TPL503 which, installed directly on the transformer, is capable of monitoring and transmitting the oil data detected TEMPERATURE, PRESSURE and LEVEL to the BB211 control unit.
L' unit of control BB211 protects the transformer by means of appropriate alarm contacts and transmits the information to a remote center for PREVENTIVE MAINTENANCE.
It is equipped with 3 indicator lights: T = Temperature, P = Pressure, L = Level for indicating alarms with bright colors.
The flashing LEDs indicate the fault conditions (FAULT) of the control unit, which has registers dedicated to the storage of possible alarms, the maximum values reached by the temperature and pressure parameters and the minimum value for the level parameter.
It also supplies the TPL 503 and receives information on the status of the transformer.
The compact dimensions and the DIN rail mounting system allow it to be installed in a wide variety of control boxes.
