Looking for reliable11kV current transformers (CTs) for your high-voltage power systems? This guide covers everything you need to know—Zorte, Spezifikatioune, Uwendungen, 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 forSchutz, metering, and monitoring. These CTs are essential inËnnerstatiounen, industriell Planzen, an erneierbar Energiesystemer to ensure safe and efficient power distribution.

Key Features of 11kV Current Transformers

✔Bewäert Spannung: 11,000V (11kV an)
✔Primary Current Range: 50A – 5000A
✔Secondary Output: 1A or 5A standard
✔Genauegkeet Klass: 0.2, 0.5, 1.0 fir Meter; 5P, 10P for protection
✔Insulation Type: Ueleg ënnerdaach, 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) CTs – 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 & Äerd Feeler Schutz (5P/10P class)

• Power Quality Monitoring

• Erneierbar Energie Systemer (Solar / Wandhaff)

11kV Current Transformer Price Range

Prices vary based ontype, Genauegkeet, and brand:

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

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

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

Factors affecting cost:

• Burden capacity

• IP Bewäertung (indoor/outdoor use)

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

Where to Buy 11kV Current Transformers?

• Global Fournisseuren: Alibaba, Schneider Electric, Toshiba

• Local Electrical Distributors (better support & warranties)

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