Abstract
A method of remotely determining an impedance of an earth connection () of a first electrical equipment () connected to a power supply network (). The method comprises receiving (), from a first measurement node () connected to the first electrical equipment, a first value of an insulation impedance of the power supply network and receiving (), from a second measurement node () connected to the power supply network, a second value of an insulation impedance of the power supply network. The method further comprises calculating () the impedance of the earth connection of the first electrical equipment using the first value of the insulation impedance of the power supply network, the second value of the insulation impedance of the power supply network and a known impedance value of an earth connection () of the second measurement node.
