摘要
Temperature monitoring system for power transformers submerged in oil applied preferentially in transformers submerged in oil and it presents several facilities in the sense of becoming temperature monitoring more reliable and safe, with highlight for the redundant measurement of temperature of the top of the oil; self-calibration of the temperature measurement entrances by means of internal references and specific electronic circuits; timing between successive activation of the groups of forced cooling when the deactivation of monitoring system on screen; internal watches with auxiliary alimentation without battery; safety reinforced in the alarms signalling for elevated temperature and finally automatic adjustment of the alarm values of the temperature differential of the commuter of derivations in load.
