Total conducted emission from a customer in the frequency range 2 to 150 kHz with different types of lighting Sarah Rönnberg, Mats Wahlberg, Math Bollen Luleå University of Technology, Sweden RÖNNBERG-SE-S

Frankfurt (Germany), 6-9 June 2011 Introduction  Domestic customer Equipment commonly used in Swedish homes were installed at a test site. A total of 32 lamps were connected  Hotel A total of 563 incandescent lamps in 76 rooms were replaced mostly LED lamps but also some CFL lamps 2RÖNNBERG-SE-S2-0173

Frankfurt (Germany), 6-9 June 2011 Four scenarios for a domestic costumer  Past All lamps are incandescent  Present Lamps are a mix of incandescent and CFLs  Future Lamps are a mix of CFLs and LEDs  Far Future All lamps are LEDs 3RÖNNBERG-SE-S2-0173

Frankfurt (Germany), 6-9 June min load pattern 4 Light 1, 2 and 3 were replaced for the four scenarios. All other equipment remained the same. RÖNNBERG-SE-S2-0173

Frankfurt (Germany), 6-9 June 2011 Emission from the hotel 9 to 70 kHz 10RÖNNBERG-SE-S2-0173

Frankfurt (Germany), 6-9 June 2011 Conclusions  CFLs and LEDs emit high frequency currents, as do other customer equipment  Customer equipment can also shunt high frequency currents  The emission seems to propagate between equipment to a higher degree than towards the grid 11RÖNNBERG-SE-S2-0173
