Abstract
The invention relates to an electronic apparatus fastened on an oil transformer, which measures with precision, continuously and simultaneously the value of the temperature, of the level of the dielectric liquid contained in the transformer, of the pressure inside the transformer and of the current-strength at the transformer secondary. With this measure of the four parameters are associated the continuous memorization of these measures over 24 hours, the visualization of these memorized measures on the apparatus or at distance on a peripheral equipment connected to the apparatus as well as the control of an alarm system and of a stop system of the transformer for each parameter.
