ZE4125 Demonstration Panel for the Study of the Protection Devices
for Safety and Continutity of Electric Power Supply
INTRODUCTION
This panel can be used by teachers for their lessons and by
students for an easy learning and testing on actual protection
electric devices that ensure the safety of both people and system,
besides the continuity and quality of electric power to power
consuming devices. The panel supplies means for verifying the rule
of art and the relevant technical standards.
The various electrical devices installed, connected partially with
each other and with safety terminals, become operating with very
simple and fast operations, offering the possibility of creating,
modifying and checking the safety devices of the installation.
The panel is made of insulating material and it represents
thesupport for the necessary devices for carrying out the testing
Programme.
The apparatuses are represented on the panel with their
standardized international symbols and, when necessary, test points
correspond to standardized educational terminals with high
protection degree against accidental contacts.
TRAINING PROGRAM:
This panel includes some innovatory electric devices for the
protection of people and of installations against the effects of
electric current that ensure continuity of power availability,
besides safety of people. The fi eld of application of these
devices includes both civil installations and those of business
and/or production (craft-industrial) sectors.
Main topics dealt with:
Protection by earthing
Protection by differential circuit breaker, automatic reset
Protection by differential circuit breaker, emergency stop in
positive safety
Protection by differential circuit breaker, double sensitivity
Switch for reducing electric fi elds (bio switch)
Coordination of antijamming protection devices
(overvoltage limiter, SPD) at several levels
Uninterruptible Power Supply (UPS) for single-phase lines
These devices can be used and studied one by one, or in
coordination with each other.
TECHNICAL SPECIFICATIONS:
Framework is made of sheet steel chemically treated and painted
with several coats of epoxy varnish; its base is provided with
rubber feet and it can be positioned on a
working top.
All the necessary electric components for the correct power supply
of circuits are included in the panel.
Main components installed:
1 differential circuit breaker; Idn = 30 mA; type A; with devices
of automatic reset
1 magnetothermal differential circuit breaker; In = 1 A; curve [C];
Idn = 0.3 A; type AC; with emergency stop circuit in positive
safety 1 power line of 230 Vac -1 A for powering auxiliary devices
1 magnetothermal differential circuit breaker of double
sensitivity; In = 10 A; curve [C]; Idn = 30/200 mA; type AC
1 switch for reducing electric fi elds (bio switch)
3 antijamming protection devices (overvoltage limiters, SPD with
current of 15 – 40 – 65 kA)
1 Uninterruptible Power Supply (UPS) for single-phase with output
rated current of 500 VA at 230 V
1 single-phase isolation transformer of 230 / 230 V 500 VA
1 simulator of user earth resistance of 1, 2, 20, 200 Ω
1 simulator of earth fault adjustable between 5 and 35 mA
1 simulator of earth fault adjustable between 100 and 300 mA
