As a leading manufacturer specializing in electrical measurement and protection equipment, Jinhua Dika Electrical Equipment Co., Ltd. is proud to introduce our 10KV High Current Toroidal Current Transformer (CT). Designed specifically for robust three-phase power systems operating at 380V, 400V, or 415V, this CT provides reliable, high-precision current measurement essential for safe and efficient power management. With over a decade of experience and a commitment to quality certified by multiple international standards, we deliver components that enhance system performance and longevity for industrial and utility applications worldwide.
The toroidal design is a key feature, offering significant advantages over traditional split-core or bar-type CTs. Its ring-shaped structure allows for easy installation around existing conductors without the need to disconnect the line, minimizing downtime and installation costs. This CT is engineered to handle high current levels in demanding 10KV environments, ensuring accurate signal conversion for metering, protection relays, and energy analytics systems.
- Robust Construction: Built with a high-grade magnetic core and precision-wound copper coils to ensure stable performance under varying load conditions and thermal stress.
- Excellent Accuracy: Provides consistent measurement accuracy across a wide current range, critical for billing, load balancing, and fault detection.
- Enhanced Safety: The insulated toroidal body and high-voltage rating contribute to safer operation in electrical panels and substations.
- Broad Compatibility: Specifically calibrated for common three-phase system voltages (380V/400V/415V), making it a versatile choice for global applications.
- Low Power Loss: Optimized design minimizes core losses, improving overall system efficiency.
- Flexible Output: Can be configured to provide standard output signals (e.g., 0-1A, 0-5A) compatible with most monitoring devices.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of a toroidal CT compared to other types?
A: The toroidal (ring-shaped) design allows the CT to be installed around an existing live conductor without cutting or disconnecting it. This makes installation quicker, safer, and less disruptive, significantly reducing downtime and labor costs.
Q2: Is this CT suitable for both 50Hz and 60Hz power systems?
A: Yes, our 10KV High Current Toroidal CT is designed to perform accurately at both 50Hz and 60Hz frequencies, making it suitable for applications worldwide.
Q3: Can the CT be used for single-phase systems?
A: While specifically optimized and calibrated for three-phase systems (380V/400V/415V), a single unit can be used on a single-phase line within a three-phase network. However, for dedicated single-phase applications, we recommend consulting with us for the most suitable product.
Q4: What output signals does this CT provide?
A: The CT typically provides standard low-current output signals such as 0-1A or 0-5A, which are compatible with most energy meters, protection relays, and monitoring devices. Other output ranges can be customized upon request.
Q5: How do I determine the correct current rating (ratio) for my application?
A: The required current ratio depends on your system's maximum expected primary current and the input range of your secondary measurement device. We can assist you in selecting the appropriate ratio based on your system specifications.
Q6: Are mounting brackets or accessories included?
A: Mounting options such as panel brackets or DIN rail adapters are available. Please specify your mounting requirements during inquiry, and we will provide the suitable configuration.
Q7: What certifications does this product hold?
A: Our manufacturing processes are certified under ISO9001, ISO14000, and OHSAS18001 among others. Specific product certifications or test reports for standards like IEC can be provided based on customer request and project requirements.
Q8: What is the typical delivery time for this product?
A: For standard models, delivery can be arranged promptly from our stock. For customized specifications, the lead time depends on the complexity of the request. We ship from major Chinese ports to ensure timely delivery to global destinations.
