The invention relates to remote activation of a communication module of a self-powered intelligent electronic device (IED). The IED controls an auto recloser mounted on an electric pole of a power distribution network. A controller of the IED, receives an activation signal from a trigger source, positioned within a predefined distance from the IED, through an optical sensor to activate the communication module. A control signal is generated, upon the controller of the IED detecting the activation signal, for powering the communication module from a power supply module. The power supply module is enabled to power the communication module for a duration controlled with the control signal. The communication module is activated for communicating a plurality of data associated with the IED to a remote communication device upon enabling the power supply module for the communication module.

Remote activation of communication modules of self-powered intelligent electronic devices

A power supply arrangement, especially in connection with a conductor ( ) of a medium-voltage overhead line, which arrangement comprises a power supply ( ) and a first and second element ( ) made of an electrically conductive material, which are connected electrically to the power supply for feeding energy to the power supply. The first element ( ) of the power supply arrangement is arranged to be close to the conductor ( ) and has a capacitance (Ce) to an element in a second potential, the capacitance being arranged to charge itself by effect of an electric field generated by the voltage of the medium-voltage conductor, and said second element ( ) is arranged to have a galvanic or capacitive connection with the conductor ( ) for feeding energy to the power supply ( ) from the potential difference between said first and second elements.
