Development of an Outdoor Integrated Low - Voltage Current Transformer
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

Ratio Trial Verification Method for Current Transformers
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

Why Does the Secondary Insulation of Outdoor Current Transformers Drop?
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
