In power grid construction, line losses reflect planning, design, and operation management. They’re key for evaluating power systems. For refined low - voltage transformer area line loss management, accurate line loss counting is critical. So, solidifying basic data, ensuring data accuracy, and proper original data collection matter for analysis. We must also optimize factors affecting collection accuracy, make preventive measures, and boost refined line loss management.1 Current Status of

I'm Echo, a 12-Year Veteran in the CT Industry, Talking About What's Coming NextHi everyone, I'm Echo, and I've been working in the current transformer (CT) industry for 12 years.From learning wiring and equipment debugging with my mentor to now leading a team tackling complex on-site issues, I've witnessed many technological advancements and industry changes. Especially with outdoor current transformers, there have been significant developments, but also much room for improvement.A few days ago

Fellow electric power calibration workers, you must have encountered this situation: The nameplate of an outdoor current transformer has been tormented by wind, sun, rain, and freezing, to the point where the transformation ratio is indistinguishable! Don't panic, we have a solution - use a current transformer calibrator and through the “transformation ratio trial calibration method”, we can figure out the actual transformation ratio and errors clearly. Here, taking the SHGQ - DC typ

I'm Felix, a 15-Year Veteran in the CT Industry, Sharing What You Need to Watch Out ForHi everyone, I'm Felix, and I've been working with current transformers (CTs) for over 15 years. Today, let’s talk about why the secondary insulation of outdoor CTs sometimes drops, and what you can do to prevent it.Common Causes:1. Moisture Ingress — Poor Sealing is the Biggest Problem!Outdoor CTs are constantly exposed to wind and rain. If the sealing isn't tight enough, moisture can get inside a

By Oliver, 8 Years in the Electrical IndustryHi everyone, I'm Oliver, and I've been working in the electrical industry for 8 years.From early days doing substation equipment commissioning to now managing protection and metering configurations for entire distribution systems, one of the most frequently used devices in my work has been the Current Transformer (CT).Recently, a friend who's just starting out asked me:“How do you test current transformers? Is there a simple and effective way to

Practical Experience Sharing from an Electrical Engineer in the FieldBy James, 10 Years in the Electrical IndustryHi everyone, I'm James, and I've been working in the electrical industry for 10 years.From early involvement in substation design and equipment selection, to later taking charge of relay protection and automation system commissioning for entire projects, one of the most frequently used devices in my work has been the current transformer (CT).Recently, a friend who's just starting out
