Abstract: A device assembly including a supply connection adapted to be electrically connected to a power source; a microcontroller; a sensor system adapted to measure at least one environmental parameter; and a supercapacitor. The device assembly has a first operating state, in which power is supplied by a first power supply link from the supply connection to the microcontroller, and a second operating state, in which power is supplied by a second power supply link from the supercapacitor to the microcontroller, and the microcontroller is alternately in an inactive mode and an active mode.

Abstract: A self-powered IED for a pole-mounted auto-recloser connected to an electric line includes a main control module and a lockout indication module. The main control module determines a fault in the electric line and trips the auto-recloser. During a permanent fault in the electric line, the auto-recloser is remained open, and the main control module activates a lockout state by generating a lockout set signal. The lockout indication module comprises a light source and super-capacitors. The super-capacitors provide stored charges to the light source when the lockout state is activated to provide notification throughout the lockout state.

Abstract: 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.
