7. Voltage Fluctuation and Flicker

7.1. Test Specification

According to EMC Standard : EN 61000-3-3

7.2. Test Setup

7.3. Limit

The following limits apply:

－ the value of P

shall not be greater than 1.0;

－ the value of P

shall not be greater than 0.65;

－ the value of d(t) during a voltage change shall not exceed 3.3 ％ for more than 500

ms;

－ the relative steady-state voltage change, d

, shall not exceed 3.3 ％;

－ the maximum relative voltage change, d

max

, shall not exceed;

a) 4 ％ without additional conditions;

b) 6 ％ for equipment which is:

－ switched manually, or

－ switched automatically more frequently than twice per day, and also has either a

delayed restart (the delay being not less than a few tens of seconds), or manual restart,

after a power supply interruption.

NOTE The cycling frequency will be further limited by the P

and P

limit.

For example: a d

max

of 6％producing a rectangular voltage change characteristic twice per

hour will give a P

of about 0.65.
