Looking for reliable11kV current transformers (CTகள்) for your high-voltage power systems? This guide covers everything you need to know—types, விவரக்குறிப்புகள், பயன்பாடுகள், and pricing—to help you make an informed purchase decision.

What is an 11kV Current Transformer?

An11kV current transformer is a precision instrument used tostep down high currents in power systems to measurable levels forபாதுகாப்பு, அளவீடு, and monitoring. These CTs are essential inதுணை மின் நிலையங்கள், தொழில்துறை ஆலைகள், மற்றும் புதுப்பிக்கத்தக்க ஆற்றல் அமைப்புகள் to ensure safe and efficient power distribution.

Key Features of 11kV Current Transformers

✔மதிப்பிடப்பட்ட மின்னழுத்தம்: 11,000வி (11கே.வி)
✔Primary Current Range: 50A – 5000A
✔Secondary Output: 1A or 5A standard
✔துல்லிய வகுப்பு: 0.2, 0.5, 1.0 for metering; 5பி, 10P for protection
✔Insulation Type: Oil-immersed, resin-cast, or SF6 gas-insulated

Types of 11kV Current Transformers

1. Wound Primary CTs – Best for low-current applications (5A-100A).

2. Bar-Type CTs – Used for high currents (200A-5000A), common in switchgear.

3. Window-Type (Ring) CTகள் – Easy to install around existing conductors.

4. Optical CTs – Advanced, non-conductive sensors for smart grids.

Applications of 11kV Current Transformers

• ஆற்றல் அளவீடு & Billing (0.2 class accuracy)

• Overcurrent & Earth Fault Protection (5P/10P class)

• Power Quality Monitoring

• Renewable Energy Systems (Solar/Wind Farms)

11kV Current Transformer Price Range

Prices vary based ontype, துல்லியம், and brand:

• Standard Protection CT (5P/10P): $100 – $500

• High-Accuracy Metering CT (0.2/0.5 வகுப்பு): $300 – $1,200

• Resin-Cast or Gas-Insulated CTs: $500 – $2,500+

Factors affecting cost:

• Burden capacity

• ஐபி மதிப்பீடு (indoor/outdoor use)

• பிராண்ட் (ABB, Siemens, GE, local manufacturers)

Where to Buy 11kV Current Transformers?

• Global Suppliers: Alibaba, Schneider Electric, Toshiba

• Local Electrical Distributors (better support & warranties)

• Used/Refurbished CTs (budget option, but inspect carefully)

Conclusion

Choosing the right11kV current transformer depends onapplication, accuracy needs, and budget. Compare specs and prices from trusted suppliers before purchasing.
