5.8.3 Performing a measurement
In this function, connection to the neutral is only obligatory for "Z

S

 

 "measurement. For “Z

S

”, the

“neutral” test lead can be connected to the earth and for “Z

i

”, it can be connected to a phase (phase-

phase loop measurement).

1. Connect the instrument according to the diagrams below.

TT System :

L-PE loop measurement enables quick earth measurement without planting an earth
testing rod (excess value).
L-N  loop measurement enables the short-circuit current to be calculated and makes
it possible to scale protective devices (fuses or circuit-breaker)

TN System : L-PE or L-N or L-L loop measurement enables measurement of fault loops and

calculation of short-circuit currents for scaling of fuses or circuit-breaker.

IT System :

Measuring L-N or L-L loops enables fault loop measurement and calculation of short-
circuit currents  for scaling of fuses or circuit-breakers. The L-PE loop cannot be
measured on account of the high impedance of the supply transformer’s earth
connection (> measurement range) , even total insulation from the earth.
