Abstract: A measurement or protective device has a terminal for establishing a connection to a data bus. A control device determine the mode of operation of the measurement or protective device, and the mode of operation can be changed from the outside using the terminal. The novel device enables evaluation operations, in particular testing operations, from the outside in an even simpler manner than before. The control device is configured in such a manner that it can operate at least two software modules in parallel and independently of one another. One of the software modules is an operating module which determines the measurement or protective mode of operation of the device, and at least one additional software module has another function. The control device has at least one software interface to which the additional software module can be coupled, in terms of software, from the outside using the terminal.

Abstract: A method for generating fault classification signals which identify faulty loops which develop in a multiphase energy supply network observed in the event of a fault from a protective device with a starting arrangement. To be able to generate such fault classification signals in a relatively simple manner, a neural network is used which is trained using input variables simulating faulty loops in the form of normalized resistance and reactance variables formed taking into consideration the starting characteristic of the starting arrangement. In the case of a fault, normalized resistance and reactance measured variables network for generating fault classification signals.
