INFORMATION
impulse conditions
Most lightning tests, used for equipment verification, specify a unidirectional sawtooth waveform which has an
exponential rise and an exponential decay. Wave shapes are classified in terms of Peak Amplitude (voltage or
current), rise time and a decay time to 50% of the maximum amplitude. The notation used for the wave shape
is amplitude, rise time/decay time. A 38 A, 5/310 µs wave shape would have a peak current value of 38 A, a
rise time of 5 µs and a decay time of 310 µs.
There are three categories of surge generator type, single wave shape, combination wave shape and circuit
defined. Single wave shape generators have essentially the same waveshape for the open circuit voltage and
short circuit current (e.g. 10/1000 µs open circuit voltage and short circuit current). Combination generators
have two wave shapes, one for the open circuit voltage and the other for the short circuit current (e.g.
1.2/50 µs open circuit voltage and 8/20 µs short circuit current). Circuit specified generators usually equate to
a combination generator, although typically only the open circuit voltage waveshape is referenced (e.g. a
10/700 µs open circuit voltage generator typically produces a 5/310 µs short circuit current). If the
combination or circuit defined generators operate into a finite resistance the wave shape produced is
intermediate between the open circuit and short circuit values.
When the TISP switches into the on-state it has a very low impedance. As a result, although the surge wave
shape may be defined in terms of open circuit voltage, it is the current waveshape that must be used to
assess the TISP surge requirement. As an example, the CCITT IX K17 1.5 kV, 10/700 µs surge is changed to
a 38 A 5/310 µs waveshape when driving into a short circuit. The impulse generators used for rated values
are tabulated below
