Abstract

The paper reports an experimental evaluation of LED lamps in terms of admittance Frequency Coupling Matrices (FCM) for harmonic modelling needs. After recalling the FCM approach, a description of the experimental setup used and an LED lamp classification previously proposed by the authors is presented. For each of the four lamp types identified, some harmonic fingerprint plots are shown to introduce the admittance characteristics. More detailed analysis of the characteristics is performed using the tensor representation of the FCM, which compares characteristics between the different lamp types and also between different lamps of the same type. It is shown that this approach can identify characteristics of different types of lamps for modelling purposes.
