TISP61089B High Voltage Ringing SLIC Protector
‘1089 Section 4.5.5 - Test Generators (Continued)
The exception to these two conditions of independence and limit waveshape values is the alternative IEEE C.62.41, 1.2/50-8/20 combination
wave generator which may be used for testing in ‘1089 Sections 4.5.7, 4.5.8 and 4.5.9. Here, the quoted waveshape values are nominal with
defined tolerance. The open-circuit voltage waveshape is 1.2

s duration. The generator fictive source impedance (peak open-circuit
voltage divided by peak short-circuit current) is 2.0

.
To get the same peak short-circuit currents as the 2/10 generator, for the same peak open-circuit voltage setting, ‘1089 specifies that the
1.2/50-8/20 generator be used with external resistors for current limiting and sharing. When working into a finite resistive load, the delivered
1.2/50-8/20 generator current waveshape moves towards the 1.2/50 voltage waveshape. Thus, although the 1.2/50-8/20 delivered peak
current is similar to the 2/10 generator, the much longer current duration means that a much higher stress is imposed on the equipment
protection circuit. This can cause fuses to operate which are perfectly satisfactory on the normal 2/10 generator. Testing with the 1.2/50-8/20
generator gives higher stress levels than the 2/10 generator and, because it is seldom used, will not be covered in this analysis.
