Looking for reliable11kV current transformers (трансформаторы тока) for your high-voltage power systems? This guide covers everything you need to know—типы, характеристики, приложения, and pricing—to help you make an informed purchase decision.

What is an 11kV Current Transformer?

Ан11kV current transformer is a precision instrument used tostep down high currents in power systems to measurable levels forзащита, измерение, and monitoring. These CTs are essential inподстанции, промышленные предприятия, и возобновляемые источники энергии to ensure safe and efficient power distribution.

Key Features of 11kV Current Transformers

✔Номинальное напряжение: 11,000В (11кВ)
✔Primary Current Range: 50A – 5000A
✔Secondary Output: 1A or 5A standard
✔Класс точности: 0.2, 0.5, 1.0 для измерения; 5П, 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) трансформаторы тока – Easy to install around existing conductors.

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

Applications of 11kV Current Transformers

• Учет энергии & Billing (0.2 class accuracy)

• Overcurrent & Защита от замыканий на землю (5P/10P class)

• Power Quality Monitoring

• Системы возобновляемой энергии (Solar/Wind Farms)

11kV Current Transformer Price Range

Prices vary based ontype, точность, 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

• IP rating (indoor/outdoor use)

• Бренд (АББ, Сименс, GE, local manufacturers)

Where to Buy 11kV Current Transformers?

• Global Suppliers: Алибаба, Шнайдер Электрик, Toshiba

• Local Electrical Distributors (better support & warranties)

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