Looking for reliable11kV current transformers (TC) for your high-voltage power systems? This guide covers everything you need to know—tipos, presupuesto, aplicaciones, 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 forprotección, medida, and monitoring. These CTs are essential insubestaciones, plantas industriales, y sistemas de energía renovable to ensure safe and efficient power distribution.

Key Features of 11kV Current Transformers

✔Tensión nominal: 11,000V (11kV)
✔Primary Current Range: 50A – 5000A
✔Secondary Output: 1A or 5A standard
✔Accuracy Class: 0.2, 0.5, 1.0 para medir; 5PAG, 10P for protection
✔Insulation Type: sumergido en aceite, 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) TC – 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 & Earth Fault Protection (5P/10P class)

• Power Quality Monitoring

• Sistemas de energía renovable (Solar/Wind Farms)

11kV Current Transformer Price Range

Prices vary based ontipo, exactitud, and brand:

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

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

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

Factors affecting cost:

• Burden capacity

• Clasificación IP (indoor/outdoor use)

• Marca (TEJIDO, siemens, GE, local manufacturers)

Where to Buy 11kV Current Transformers?

• Proveedores globales: Alibaba, Electricidad Schneider, Toshiba

• Local Electrical Distributors (better support & warranties)

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

Conclusión

Elegir lo correcto11kV current transformer depende deapplication, accuracy needs, y presupuesto. Compare specs and prices from trusted suppliers before purchasing.
