The «Electrical Installation» demo case can be used to simulate the different types of neutral systems characteristic of the
electrical systems encountered in domestic, tertiary and industrial environments:
TT system
TN-S or TN-C system
IT system
Depending on the measuring instruments used with this demo case, it is possible to measure:
Earth / Resistivity
Differential systems
Insulation
Phase-neutral or phase-earth loop
Continuity
For each neutral system, certain faults can be simulated:
Phase outage
Neutral cut-off
Earth cut-off
Neutral-earth inversion
Phase-earth leakage current (4...34 mA)
In its robust site casing suitable for all conditions in the field, it is easy to transport from one place to another thanks to its fold-away
handle.
A depressurization valve (unscrewable black button near the handle or two holes under the handle, depending on the series) also
allows you to take it on aircraft without worrying about opening the case when you arrive, despite the wide pressure variations.
