6.3.2
PF, THD and ballast efficiency
The power factor, total harmonic distortion of current and ballast efficiency are measured
and the results are shown in Table 4, 5, 6, and 7.
6.3.3
Electromagnetic compatibility
The EMC tests have been performed according to the EN55015 standard (Limits and
methods of measurement of radio disturbance characteristics of electrical lighting and
similar equipment).
The Agilent E7401A EMC Analyzer has been used as test equipment.
