Why are your machines failing when all measurements look normal? Discover how invisible high-frequency noise (supraharmonics) can silently damage your system.

In this article, we want to highlight a concept that many organizations still overlook—yet it has a direct impact on their true costs: Energy Cost Allocation. Energy Cost Allocation is the process of distributing energy expenses from a single utility bill to sub-units such as production lines, departments, or even down to the product level (Product SKU), so that the actual energy cost of each part can be clearly seen. ⚡ Looking at a Total Bill Is Like Driving Without a Dashbo

When starting to talk about energy saving, the first question should not be how to reduce it. Instead, it should be: 👉 Do you really understand how your electricity bill is calculated? This may seem basic to some, but in real operations, those responsible for electricity costs do not always have a direct background in energy. And without a clear understanding of the billing structure, energy-saving initiatives may end up solving the wrong problem. 📌 As mentioned in previous

This article questions a common but often unexamined approach in industrial energy projects: starting energy savings by purchasing solutions too early. From real field experience, many factories already have data, equipment, and systems. What is often missing is clarity—how the data will be used, who has decision authority, and when actions should be taken. As a result, systems are monitored but rarely used for real decision-making. The article compares two factories with s

Based on our experience in assisting customers with harmonic analysis across many facilities, both within industrial plants/Building and at the Point of Common Coupling (PCC),as well as through discussions with responsible personnel at various levels,we have found that: If operators are able to correctly understand and interpret measurement results, this will lead to decisions that are aligned with the actual condition of the electrical system. 🎯 Objective of This Article Th

Understand Voltage Sag Graphs with Ease—Gain Insights to Analyze, Plan, and Make Better Decisions At Truewatts, we’ve had the opportunity to support many clients in analyzing data from Power Quality Meters (PQ Meters), especially when dealing with voltage sags or dips. Quite often, the questions that follow are: 👉 “What exactly does this graph mean?” 👉 “How can we make practical use of this data?” This article walks you through how to interpret Voltage Sag/Dip graphs effec

Case Study: Solar PV vs.Power Factor Location: A Manufacturing Facility The origin of this article began when a factory received information suggesting that the newly installed solar PV system might have an impact on the power factor. This raised concerns among the stakeholders, leading the factory to also seek greater visibility into the performance of the solar system itself. In this case, Truewatts stepped in to support both the factory and the investor/EPC by analyzing t

When it comes to electrical systems, Power Factor (PF) is one of the key indicators used to measure how efficiently energy is being utilized. PF tells us how effectively electrical equipment or the overall system uses the power it receives. When the Power Factor is close to 1.0 (or 100%), it means the electrical system is operating at maximum efficiency with minimal energy loss. However, when the Power Factor drops, it negatively impacts energy efficiency, which may lead to p

QC, or Quality Control, is a process that ensures the quality of production is inspected, maintained, and improved. QC helps reduce errors, increase customer satisfaction, and lower costs. It is also a key strategy that enhances efficiency and sustainability in business. In energy management systems, QC is also necessary to ensure inspection, maintenance, and improvement. The concept of MT&R (Monitoring, Targeting, and Reporting) is applied for quality control in this context

IEC 61000-4-30 is a standard that defines the measurement methods and parameters for power quality instruments used in power systems with a fundamental frequency of 50 Hz or 60 Hz. This standard ensures that power quality monitoring instruments from different manufacturers use the same definitions and standardized measurement techniques for power quality parameters such as sag, swell, frequency, interruption, flicker, unbalance, harmonics, interharmonics, and the 2 kHz–150 kH
