What is a ZE test?
`ZE` is a measurement of the external earth fault impedance of the installation. It is the measured resistance of the supply transformer winding, the supply phase conductor, and the earth return path of the supply. `ZE` can be obtained by enquiry to the electricity supplier or by direct measurement at the supply.
