Looking for reliable11kV current transformers (CT) pour vos systèmes électriques haute tension? This guide covers everything you need to know—genres, caractéristiques, candidatures, and pricing—to help you make an informed purchase decision.

What is an 11kV Current Transformer?

Un11kV current transformer is a precision instrument used tostep down high currents in power systems to measurable levels forprotection, mesure, and monitoring. These CTs are essential insous-stations, installations industrielles, et systèmes d’énergies renouvelables to ensure safe and efficient power distribution.

Key Features of 11kV Current Transformers

✔Tension nominale: 11,000V (11kV)
✔Primary Current Range: 50A – 5000A
✔Secondary Output: 1A or 5A standard
✔Accuracy Class: 0.2, 0.5, 1.0 pour le comptage; 5P., 10P for protection
✔Insulation Type: Immergé dans l'huile, 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) CT – Easy to install around existing conductors.

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

Applications of 11kV Current Transformers

• Energy Metering & Billing (0.2 class accuracy)

• Overcurrent & Protection contre les défauts de terre (5P/10P class)

• Power Quality Monitoring

• Systèmes d'énergie renouvelable (Parcs solaires/éoliens)

11kV Current Transformer Price Range

Prices vary based ontaper, accuracy, and brand:

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

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

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

Factors affecting cost:

• Burden capacity

• Indice IP (indoor/outdoor use)

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

Where to Buy 11kV Current Transformers?

• Global Suppliers: Alibaba, Schneider Électrique, 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, et budget. Compare specs and prices from trusted suppliers before purchasing.
