These images depict the measurement of the external earth fault loop impedance or Ze.

This test is performed to ensure that there is an earth connection and also to make sure that the value measured is equal to or less than the electrical supplier’s quoted Ze and or the design calculations.

This measurement is taken by using a calibrated earth fault loop impedance tester conforming to parameters specified in the current regulations.

These images depict the measurement of the prospective short circuit current or PSCC on one 100A phase of a 3 phase 300A supply.

The values obtained in the measurement of the PSCC are compared with the breaking capacity of protective devices in order to ensure the correct specification of components and a safe installation.
