Looking for reliable11kV current transformers (CT) 高電圧電力システム向け? This guide covers everything you need to know—types, 仕様, アプリケーション, 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 for保護, 測光, and monitoring. These CTs are essential in変電所, 産業プラント, および再生可能エネルギーシステム to ensure safe and efficient power distribution.

Key Features of 11kV Current Transformers

✔定格電圧: 11,000V (11kV)
✔Primary Current Range: 50A – 5000A
✔Secondary Output: 1A or 5A standard
✔Accuracy Class: 0.2, 0.5, 1.0 計量用; 5P, 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) CT – Easy to install around existing conductors.

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

Applications of 11kV Current Transformers

• エネルギー計測 & Billing (0.2 class accuracy)

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

• Power Quality Monitoring

• Renewable Energy Systems (Solar/Wind Farms)
