Abstract
A management device (1) of the causes of tripping in an electronic trip device enabling operation to take place in efficient and dependable manner by means of an architecture with three microcontrollers. The first microcontroller (3), second microcontroller (4) and third microcontroller (5), connected to one another, perform analysis and storage of characteristics typical to the electric power system (2) measured by the first microcontroller (3). Depending on the power supply situations and the analyzed events, one, two or three microcontrollers can be active to reduce the electric power requirements of the device (1). Storage of the data concerning the electric power system (2) is at least partially performed in redundant manner.
