What Makes a Power Quality Problem Worth Solving?
Published by Dranetz Technologies, Inc. Tech Tip: What Makes a Power Quality Problem Worth Solving?, Website: Dranetz.com Most power quality events won’t shut you down. But when they do, they cost more than just a headache. The challenge isn’t detecting power quality problems. That’s the easy part. The real question is: Do those issues actually matter to your operation? A dip, a transient, a bit of harmonic distortion—none of these are problems on their own. They’re only problems if your systems are vulnerable to them. Let’s walk through how to determine that, and why proactive monitoring saves more than it costs. What’s a Power Quality…

But knowing which ones apply, especially in the U.S., isn’t always straightforward. This article will walk you through the key differences, why measurement consistency matters, and how to choose the right meters to get accurate, defensible data.…
Keep readingA VECM Analysis of the Impact of Economic Growth and Investment on Electricity Consumption in Indonesia
Published by Andi Abdul Halik LATEKO1, Yusri Syam AKIL2, Universitas Muhammadiyah Makassar (1), Hasanuddin University (2) ORCID: 1. https://orcid.org/0000-0002-9002-131X Abstract. This paper employs a Vector Error Correction Model (VECM) analysis to investigate the influence of economic growth (GDP) and investment (FDI) on electricity consumption (EPC) in Indonesia. By examining annual data from 1971-2019, the study explores the short-term dynamics and long-run equilibrium relationships among the variables. A negative relationship is observed between EPC and GDP in the long run, while a negative relationship exists between EPC, GDP, and FDI in the short term. The short-run analysis reveals that GDP significantly…

The continuous rise in electricity consumption and the integration of renewable energy sources into distribution grids are gradually posing challenges to conventional protection systems. This trend significantly impacts traditional centralized methods of electricity generation, shifting towards local production and consumption and moving closer to emerging microgrids. This aspect was specifically considered during the development of the current power system we…
Keep readingData Center Commissioning Case Study
Published by Dranetz Technologies, Inc. Website: Dranetz.com Most high reliability facilities have a significant investment in UPS systems, generators and other mitigation devices in order to prevent electrical supply problems from impacting their business. However, these mitigation devices and related equipment are complex electro-mechanical systems that are themselves susceptible to failure and often do not provide any alarms or notifications when not functioning up to manufacturers specifications. That’s where continuous power monitoring comes in. Power Quality monitoring systems continually evaluate the health of the electrical supply at key locations within a facility including the utility supply, generators, UPS input and outputs and…
Keep readingOvervoltage on the High and Low Side Electrical Network Voltage 35 kV When Appearing and Disconnecting Short Circuits of Various Forms at Its High Voltage Part
Published by Nahid MUFIDZADA1, Gulgaz ISMAYILOVA2, Azerbaijan State Oil and Industry University ORCID: 1. 0000-0003-4063-2128, 2. 0000-0003-0063-2020 Abstract. Overvoltage is explored on the 35, 10 and 6 kV sides of the electrical network where various characters short circuit occur on its highvoltage part. It has been revealed that the overvoltage which occurs during a short circuit has the highest values if the short circuit is single-phase, as expected. However, disconnecting of all types of short circuits results in higher, overvoltage because the network operates with an isolated neutral and a short circuit. Even when a short circuit occurs on the…
