10/700 µs waveform surge - lightning simulation
This test concerns the 10/700 µs waveform surge ±1.5 kV.The surge generator used for the
test has the following circuitry
Figure 6.
The behaviour of the TSI to this lightning surge is given below
These curves show the peak voltage the surge generates across the TSI + and - terminals.
This lasts a short time ( 2 s) and after, as the internal protection behaves like a short circuit,
the voltage drop across the TS1 becomes a few volts. In the meantime all the surge current
flows through the protection device.
As far as the 10/700 µs waveform surge test is concerned,the TSI withstands the ±1.5 kV
test.
