The National Energy Regulator of South Africa (NERSA) stands at a critical crossroads in the nation’s energy landscape. Tasked with overseeing the electricity, piped-gas, and petroleum pipelines sectors, NERSA’s mandate is clear: to ensure a reliable, efficient, and sustainable energy supply for the country. Yet, in the face of South Africa’s deepening electricity crisis, NERSA’s […]
Category Archives: Power Quality Monitoring
Power Quality Monitoring is concerned with issues such as detecting phase imbalances and particularly whether all phasors have the same magnitude and are phase-shifted symmetrically by 120-degrees to each other.
For more than a year, I’ve passionately explored and shared insights into the critical issues of power quality and its financial ramifications. I’ve delved into the intricacies of unbalanced network conditions and the substantial costs these imbalances impose on electricity bills. Yet, despite my numerous articles and detailed explanations, the concepts still seem to elude […]
Please take a moment to review this important document and explore the links within it. Introduction The concept of “power quality” may seem abstract, especially when dealing with an intangible commodity like electricity. However, for commercial and industrial facility managers, it holds significant importance. Good power quality directly impacts productivity and employee safety. Conversely, poor […]
Peruse this document for a more comprehensive understanding of the subject addressed in this paper. While power electronics equipment can enhance efficiency and control, they can also cause distortions in the power system, leading to power quality issues. Harmonics, which distort the standard sinusoidal waveform of power, can result in various problems such as equipment […]
What could possibly prompt Eskom or any power distribution companies to look into issues of unbalanced power networks? Could it be the threat of legal proceedings? I understood that a representative from Eskom was notified about potential network imbalances at the Modderbee municipal substation, but it might have been disregarded as unlikely. However, since I […]
The modern power network stands at a crossroads, grappling with an unprecedented shift in energy dynamics. As the global push for sustainability accelerates, traditional grids are being challenged by the rise of decentralized, renewable energy sources, unpredictable demand patterns, and evolving technological advancements. The power network is in flux—requiring innovative solutions to balance intermittency, ensure […]
On the 2nd of October 2023, I published an article with the heading “Phase Imbalance in Distribution Networks” in which I stated that “In a recent unrelated “survey”, I came across a 10-minute averaged voltage unbalance of 327% between Phase 2 and Phase 1”. I also asked the question: is Eskom aware what is happening […]
The global shift towards renewable energy sources has brought about significant structural changes in electrical power transmission. With the increase in buying and selling electricity across vast distances, high-voltage direct current (HVDC) transmission systems have become an essential component in modern grids. Both HVDC systems and solar power generation rely extensively on power electronics devices […]
