  • Method and system for estimation of source impedence on electrical distribution lines
    Patent number: 8050878
    Abstract: A device and method for dynamically determining an impedance of a network is disclosed. The device includes at least a processing system for measuring a network voltage and network current when said network is determined to be in a first state, measuring a network voltage when said network is determined to be in a second state, estimating said impedance value dependent upon said measured voltages and current, adapting said estimated impedance based on at least one prior impedance value and storing at least said adapted impedance.
    Type: Grant
