Device for measuring impedance of electrical system has electrical conductors, load and measuring points whereby load to be measured is not at position near to measuring points and additional conductors can also be used

摘要

The device has electrical conductors (11) forming electrical circuit to which load (20) is connected whereby the conductors are of single phase or neutral phase (13) and through which measuring points can be connected. The measuring points are not necessarily located at the position where load is to be measured. Additional conductors (32) can also be used to connect the load with the measuring points (30).
