what are the transformers protections?
THE ARE MANY DEVICES ARE TO PROTECT TRANSFORMERS?
PROTECTIONS OF TRANSFORMERS
WHICH IS ? Power transformer intrinsic protections are the equipment's own protections and comprise: 50 ° C 100 TREE PBOX 747 150 WINDING TEMPERATURE DETECTOR RELAY ISOLATING OIL TEMPERATURE DETECTOR MINI BUCHHOLZ RELAY. RELAY OIL LEVEL PRESSURE RELIEF VALVE
PRESSURE RELIEF VALVE In case of lack, the internal pressure
of the transformer suddenly increases, therefore, this protection has the
purpose of reducing the internal pressure of the equipment avoiding damage to
its housing.
WINDING TEMPERATURE DETECTOR RELAY This system can reproduce
the temperature of the windings based on the rated current of the equipment by
turning off the transformer output, avoiding damage due to the excessive
temperature of the windings. 50 ° C 100
INSULATING OIL TEMPERATURE DETECTOR RELAY This equipment
indicates the temperature of the insulating oil at the top of the
transformer. They are responsible for
triggering the forced ventilation, alarm and disconnecting the transformer
output. 2 highest temp fault sensor internal fault
GAS DETECTOR RELAY (BUCHHOLZ) Detects internal problems of
the transformers, disconnecting the power supply to the MIN equipment. MAX DUBS.
MAGNETIC INDICATOR OF OIL LEVEL / ACCEPTED OIL LEVEL INDICATOR WONOPO
INDICATOR OF OIL LEVEL It has the purpose of informing if the oil volume of the
equipment has reached critical levels, being able to give alarms that guided
the operators and maintenance personnel.
