Enwei Electric CT/VT Product Overview: Options and Applications
Instrument transformers are the signal foundation for metering and protection. Choosing the right CT/VT is primarily about matching application intent (billing vs protection), burden, and installation constraints. This overview summarizes how Enwei Electric CT/VT products fit common MV and LV applications and what inputs help finalize a correct selection.
Current Transformers: Typical Options and Use Cases
CTs are used for:
- metering and monitoring
- overcurrent and earth-fault protection
- specialized protection schemes where saturation performance matters
Selection is driven by ratio, accuracy class, burden, and the expected fault level.
Voltage Transformers: Typical Options and Use Cases
VTs are used for:
- voltage measurement for meters and power calculations
- voltage-based relay functions (UV/OV, directional, synch-check)
- monitoring and recording
Selection is driven by voltage class, insulation level, ratio, accuracy class, and burden.
What Project Inputs Help Select the Right CT/VT
- System class: MV voltage level and insulation requirements
- Application intent: billing metering, monitoring, protection scheme
- Burden assumptions: devices + wiring length
- Installation constraints: indoor/outdoor, switchgear interface, available space
- Fault level: for protection CT performance requirements
