APPLICATIONS INFORMATION
deployment
These devices are three terminal overvoltage protectors. They limit the voltage between three points in the
circuit. Typically, this would be the two line conductors and protective ground (Figure 11).
In Figure 11, protectors Th2 and Th3 limit the maximum voltage between each conductor 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.
Manufacturers are being increasingly required to design in protection coordination. This means that each
protector is operated at its design level and currents are diverted through the appropriate protector e.g. the
primary level current through the primary protector and lower levels of current may be diverted through the
secondary or inherent equipment protection. Without coordination, primary level currents could pass through
the equipment only designed to pass secondary level currents. To ensure coordination happens with fixed
voltage protectors, some resistance is normally used between the primary and secondary protection. The
values given in this data sheet apply to a 400 V (d.c. sparkover) gas discharge tube primary protector and the
appropriate test voltage when the equipment is tested with a primary protector.
impulse testing
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.
