    摘要: The disclosure relates to a process of configuring a standalone self-supplied numeric controlled relay for providing phase and earth over current protection to electrical systems by accurate current measurement. The arrangement for current measurement with control algorithms is provided for power control by providing amplified and conditioned current for optimization between the current to power an electronic circuit and the fidelity of a measured current waveform so that they both are at the acceptable levels at the same time. This disclosure describes the current sensing and associated algorithm for power control in a truly self-powered relay.

    摘要: Device for powering one or more electric/electronic devices operatively associated with a low-voltage circuit breaker, comprising means for taking energy from a power supply line, electronic regulating means for receiving the energy collected by said means for taking power as input and delivering as output to the electric/electronic device a power supply voltage (Vout) having a value within a preset range with respect to a reference voltage (VR), characterized in that said electronic regulating means comprise:
    - energy storage means chargeable by means of said energy collected, at the terminals of which a voltage (VCL) is established that is indicative of the power supply voltage (Vout) delivered to the electric/electronic device;
    - a circuit for enabling/disabling the charging of the storage means;
    - a feedback circuit that receives a signal indicative of the voltage (VCL) at the terminals of the storage means and that sends a signal to the enabling/disabling circuit to trigger the disabling or enabling of the charging process in order to keep the value of the voltage at the terminals of the storage means within said preset range, said feedback circuit enabling the charging phases so as to power the storage means continuously up until the value of the voltage at their terminals comes within the preset range.

    摘要: A protection relay is disclosed that generates a trip signal to operate a circuit breaker in case of a fault condition. A first module provides measurement and analysis of power parameters of the power line connecting the power equipment that is being protected, the protection being provided by generating a first trip signal for operating a circuit breaker connected in the power line. One or more second modules can boost performance of the protection relay by measurement and analysis of power parameters-to generate a second trip signal for operating a circuit breaker connected in the power line. The first trip signal and the second trip signal are logically combined to generate a trip signal that operates the circuit breaker.
