Zusammenfassung: | The proposed short circuit indicator with memory contains a short-circuit current transducer, a voltage transducer, a threshold unit with a storage element, and additionally, a transmit-receive antenna, a switch for selecting signal reception or transmission mode, a signal transmitter, an address check unit, a unit for processing response signals, a modulator, and a power amplifier. The outputs of the short-circuit current transducer and the voltage transducer are connected to the corresponding inputs of the threshold unit, which output is connected to the first input of the switch via the modulator, power amplifier, and signal transmitter that are connected in series. The second input and the first output of the switch are connected to the transmit-receive antenna. The input of the unit for processing response signals is connected to the second output of the switch via the signal receiver and the address check unit that are connected in series. |
