APPLICATIONS INFORMATION
Impulse Testing
These devices are two terminal overvoltage protectors. They may be used either singly to limit the voltage between two conductors (Figure 11)
or in multiples to limit the voltage at several points in a circuit (Figure 12).
In Figure 11, protector Th1 limits the maximum voltage between the two conductors to ±V(BO). This configuration is normally used to protect
circuits without a ground reference, such as modems. In Figure 12, protectors Th2 and Th3 limit the maximum voltage between each conduc-
tor and ground to the ±V(BO) of the individual protector. Protector Th1 limits the maximum voltage between the two conductors to its ±V(BO)
value. If the equipment being protected has all its vulnerable components connected between the conductors and ground, then protector Th1
is not required.
To verify the withstand capability and safety of the equipment, standards require that the equipment is tested with various impulse wave forms.
The table below shows some common values.
Series resistance can be added to cover situations where either the TISP4360H3BJ current rating will be exceeded or excessive wiring
currents result or both.
When a primary protector is used, the TISP4360H3BJ may operate before the primary protector. With the TISP460H3BJ in a low voltage state,
the primary protector is prevented from working. High currents, which should have been carried by the primary protector, now flow through the
wiring to the equipment and through the TISP4360H3BJ. Interference and network equipment damage can occur, particularly if the currents
are diverted to the local ground. Protector coordination prevents this problem. A series resistor can be used to develop a voltage drop large
enough to activate the primary protector. If the primary protector was a gas discharge tube (GDT) with a maximum d.c. sparkover of 400 V and
the typical lightning impulse decay time was several hundred microseconds (TISP4360H3BJ rating 200 A), a 2 series resistor (400 V/200 A)
would be sufficient to achieve coordination. At peak currents of 200 A and above, the resistor would develop at least 400 V and GDT would
switch and divert the current.
