The MAVO-FSA function expands the MAVOWATT 45 to include a
flickermeter function.
Flicker is defined as the subjective impression made by fluctuations in
brightness at
lighting appliances caused by
fluctuations in the power supply.
Fluctuations of this sort can be acquired and evaluated with the help
of a flickermeter.
EN 61000-4-15 defines the basic functional principle of a flickermeter,
which simulates
the complex chain of events which takes place at the lamp, the eye and
the brain, and
which correlates measurement results to an experimentally determined
limit value curve
(perceptual limits).
Values for the resulting measured quantities, Pst (short-term flicker
intensity, 10 min.)
and Plt (long-term flicker intensity, 2 hours,) are simultaneously
determined for all
three phase voltages on an individual basis. An evaluation of line
voltage quality as
regards flicker can be carried out in accordance with EN 5016 based
upon these measured
values.
Furthermore, the function also acquires the largest relative voltage
fluctuation (dmax)
which occurs during the short-term measuring interval, relative
constant voltage
fluctuation (dc) and, for voltage changes of less than 3%, the maximum
deviation duration
(dt>3%).
These measured quantities are required for type testing for electrical
devices per EN
61000-3-3.
Observance of the limit values set forth in this standard is required
as of 1 January 2001
for application of the CE mark to electrical and electronic equipment
and devices with
input current of up to 16 A.
