many people will make the same mistake in using lightning surge generator, that is, the test speed is too fast in the process of test, so today’s editor will tell you what we should pay attention to in the process of using lightning surge generator to test, so as to avoid our operational mistakes
the following points should be paid attention to in the lightning surge generator test:
1. before the test of lightning surge generator, be sure to add connection measures according to the manufacturer’s requirements for lightning surge generator.
2. the test rate of lightning surge generator shall be once per minute, which should not be too fast, so as to provide a performance recovery process for lightning surge generator. in fact, the phenomenon of lightning strike in nature and the switching of large switches in switchyard cannot have a very high repetition rate.
3. lightning surge generator test is generally conducted for 5 times for positive / negative polarity.
4. the test voltage of lightning surge generator should be gradually increased from low to high, so as to avoid the non-linear characteristics of volt ampere of the test object. in addition, it should be noted that the test voltage should not exceed the requirements of the product standard to avoid unnecessary damage.
