-
Product Description: A high-precision, through-bolt type current transformer designed for revenue metering and advanced protective relaying in high-voltage substations.
-
Technical Specifications: Ratio: 3600:5 A. Accuracy Class: 0.3 (Metering) / 5P20 (Protection). Rated insulation level: 36 kV. Frequency: 50/60 Hz.
Detailed content
-
Material Composition: Core made of grain-oriented silicon steel laminations to minimize losses. Primary and secondary windings use high-purity copper. Porcelain or polymer insulator housing.
-
Structural Features: “Through-core” design requires no primary winding connections; bus bars pass directly through the core window. Includes test tap terminals (TRT) for polarity verification.
-
Safety Warning: Never open-circuit the secondary terminals while the primary is energized, as this induces extreme high voltage. Always short the secondary terminals before removing metering devices.
