Loop tester

V : voltage of the generator (electrical network supply voltage transformer)
G
(internal impedance of transformer is X-Form)

Z : impedance of the line wire from the transformer up to the test point (Z
L
displayed by instrument also includes X-Form). If this impedance is too high,
check the connections of the line wiring, the quality of the line wiring and the
switches / contacts in the line circuit.

Z : impedance of the neutral wire from the transformer up to the test point. If
N
this impedance is too high, check the connections of the neutral wiring, the
quality of the neutral wiring and the switches / contacts in the neutral circuit.

Z : impedance of the earth wire including the earth impedance itself, as seen
E
by the protection system. Similar checking, specially at the bounding points
should be done if this path impedance is too high.

PSC , PSC : prospective short circuit current (L-N and L-E)
L-E L-N

V , V : voltage between L-N & L-E
L-N L-E
Please note : instrument accuracy depend of V
1 – wiring connectors L, N, E (Line, neutral and earth)
2 – display
3 – wiring correct and not correct indicators
4 – button to turn on instrument, start the test and read different results
