3. CLP200M TESTS RESULTS ACCORDING TO

CCITT K20 RECOMMENDATIONS

3.1 CCITT K20 Recommendations

In respect with the CCITT recommendations, the

CLP200M has to withstand three kinds of distur-

bances.

3.1.1. Lightning simulation

(Test 2, table 2/K20)

This test shall be done in transversaland longitudi-

nal modes as shown in figure 10.

The test generator is the 10/700

µs with 4kV of

peak voltage.

3.1.2. Power induction

(Test 3a and 3b, table 2/K20)

Two kinds of tests using the same circuit topology

(see fig.11) are defined in the CCITT K20.

Test 3a :

Vac(max) = 300VRMS, R1 = R2 = 600

Ω

S2 operating and test duration = 200 ms.

Test 3b :

Vac(max) = 300VRMS (*), R1 = R2 = 200

Ω

S2 operating and test duration not defined.

(*) Recommended value.

3.1.3. Power contact (Test 3, table 1/K20)

This test shall be done with the test circuit of figure

12.

Vac(max) = 220VRMS , with switch S in each posi-

tion and duration 15 min.

3.1.4. Acceptance criteria and number of tests

For the tests described in chapter3.1.1., 3.1.2. and

3.1.3. two criteria are defined :

A: Equipment shall withstand the test without dam-

age and shall operate properly within the specified

limits.

B: A fire hazard should not occur in the equipment

as a result of the tests.

The criteria are affected to the different tests as

mentioned in the table 1.
