3.2. Ringing mode
3.2.1. Lightning simulation test
Lightning phenomena are the most common surge
causes. The purpose of this test is to check the ro-
bustness of the CLP200M against these lightning
strikes.
Figures 14 and 15 show that the remaining over-
voltage does not exceed +/- 260 V. The CLP200M
switches on within 0.7
µs and withstandsthe 100 A
given by the CCITT K20 generator.
Consequently,the CLP200M totally fulfills this test.
3.2.2 Power induction
(Test 3a and 3b table 2/K20)
Surges of long duration with medium voltage value
are mainly produced by the proximity of a sub-
scriber line with an AC mains line or equipment.
The purpose of this test is to check the robustness
of the CLP200M against these capacitive coupling
disturbances.
