Energy efficiency has garnered extensive interest over the past decade. Hence, transformer efficiency in distribution networks has been widely studied. A few researchers believe that more efficient transformers must be considered, whereas others believe in making improvements in distribution network characteristics to be able to make the most out of distribution transformers. The advantages and disadvantages of Compact Fluorescent Lamps (CFLs) and Light Emitted Diode (LED) Lamps from an energy perspective have been debated quite effectively in literature. As the power utilities and their customers are showing increased concern about energy efficiency and power quality, some mixed feelings toward new household lamps exist. Thus, the effect of harmonic distortion owing to CFLs’ and LEDs’ extensive usage was studied.

In this webinar, CFL and LED are first introduced with a focus on their vital electric characteristics. Subsequently, transformer de-rating under non-sinusoidal conditions from the standard point of view is investigated. Additionally, the current harmonic levels of the lamps were measured using a power quality analyzer. Transformer loading was calculated and simulated for both the CFL and LED loads. Finally, the effect of CFLs on transformer de-rating is compared to that of the LEDs.

Key takeaway from this webinar:

  1. Be able to evaluate transformer efficiency and derating in the case of non-sinusoidal loads.
  2. Be able to analyze the effects of various types of lamps on transformer losses.
  3. A combination of CFLs and other types of lamps are recommended to minimize harmonic distortion levels.

More about the presenter:

Mohammad Salay Naderi (M’10 – SM’11) did his B.Sc. (1996), M.Sc. (1998), and Ph.D. (2006) in the field of electric power engineering at Sharif University of Technology (SUT). In 2004, he joined the energy systems research group in the school of electrical engineering and telecommunications (EE&T) at UNSW as a visiting research associate and completed his PhD research work. He worked with Iran power generation, transmission, and distribution management company (Tavanir) as the deputy managing director of the bureau of technical and administration of transmission network with effect from 2005 to 2010. In 2010, he joined the school of EE&T at UNSW as a lecturer in the energy systems group. Subsequently, in 2013, he joined MicroTex Labs and worked as a principal electrical engineer and simultaneously an engineering manager in the field of renewable energy sources. He led a team to complete the installation, advance testing, and commissioning of PV+BESS systems in the ME region.

In addition, he was an international consultant at the university of Nazarbayev, Kazakhstan, with effect from Jan. 2018 to Dec. 2021. The consultation scope was in the areas including smart energy solutions, development and requirements of smart cities, power products manufacturing, high voltage engineering, condition monitoring of power equipment, and sustainable energy systems analysis and development. He served as the executive technical officer for investment plans and financial engineering of transmission network at Tavanir with effect from Feb. 2021 to Dec. 2022.

He has been serving as the Managing Director at Smart Energy Solutions Group (SESG) Pty Ltd since 2016, where he has been involved in developing and executing the company’s business strategies, preparing and implementing comprehensive business plans to facilitate achievement, and acting as the public speaker and public relations representative of the company. In 2023, he joined Engineering Institute of Technology (EIT) as an online instructor.
