3.Key Features & Advantages
1. High Precision & Stability
Engineered with advanced electromagnetic design, this product maintains ≤0.5% ratio error even under fluctuating loads, ideal for revenue metering and protective relaying.
2. Compact & Durable Design
The epoxy resin encapsulation provides IP67 protection, making it resistant to moisture, dust, and partial discharge—perfect for retrofitting older substations with limited space.
3. Smart Grid Compatibility
Equipped for integration with digital architectures (IEC 61850-ready), it supports real-time monitoring in IoT-enabled power systems.
4. Low Energy Loss
Optimized core materials reduce hysteresis and eddy current losses by up to 30%, aligning with ISO 50001 energy efficiency goals.
4.Real-World Applications
Be used in a wide range of industries.
Industrial Plants
Eliminate power factor penalties in CNC machines and assembly lines while handling surge currents up to 100x rated capacity.
Substation
Stabilizes substation voltage against harmonics and intermittent generation from renewable inverters.
Commercial Buildings
Retrofit aging systems in hospitals or malls with silent (<45dB), flame-retardant capacitors that meet NFPA 70 fire codes.
5.How It Works？
The 24kV Indoor Voltage Transformer(Potential transformer) steps down high primary voltage (24kV) to a standardized secondary output (480V,380V,220V,110V and so on, based enduser's requirement) via electromagnetic induction. Its fully enclosed structure uses layered silicon steel cores and precision-wound copper coils to minimize phase displacement (<30 minutes).
6.Manufacturing & Quality Assurance
