4.4. Voltage Fluctuation and Flicker
4.4.1. Limit
The following limits apply:
-- the value of P
st
shall not be greater than 1.0;
-- the value of P
lt
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
c
, 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
st
and P
1t
limit.
For example: a d
max
of 6％producing a rectangular voltage change characteristic twice per
hour will give a P
1t
of about 0.65.
c) 7 ％ for equipment which is:
-- attended whilst in use (for example: hair dryers, vacuum cleaners, kitchen equipment such as
mixers, garden equipment such as lawn mowers, portable tools such as electric drills), or
-- switched on automatically, or is intended to be switched on manually, no more 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.
P
st
and P
1t
requirements shall not be applied to voltage changes caused by manual switching.
