What Is High Voltage Current/Voltage Transformer？
El condensador de potencia en derivación de alta tensión ZHIMING es un condensador de potencia avanzado y confiable diseñado para aplicaciones industriales y de servicios públicos. Diseñado para funcionar de manera eficiente en sistemas de alimentación de CA de 50 Hz o 60 Hz, desempeña un papel crucial en las redes de condensadores de corrección del factor de potencia, ya que ayuda a mejorar la eficiencia energética, estabilizar los niveles de tensión y reducir las pérdidas generales del sistema. Al mejorar el factor de potencia y optimizar la gestión de la potencia reactiva, este condensador no solo aumenta la capacidad de la infraestructura eléctrica existente, sino que también prolonga la vida útil de los equipos conectados. Cumple con la norma internacional IEC 60871-1:2005 y es un producto de ahorro energético reconocido a nivel nacional, adecuado para una amplia gama de entornos de alta demanda.

Why Choose ZHIMING's High Voltage Current/Voltage Transformer?
High Accuracy & Reliability
ZHIMING uses premium-grade silicon steel cores and precision winding technology, ensuring Class 0.2/0.5 accuracy for both current and voltage transformation, minimizing metering errors.
Robust Insulation Design
Our High Voltage Current/Voltage Transformer adopts vacuum epoxy resin casting or oil-impregnated paper insulation, providing excellent dielectric strength and partial discharge control, suitable for up to 245kV and beyond.
Wide Operating Range
Designed for extreme temperatures (-40°C to +55°C), high altitude, and humid environments, ZHIMING products maintain stable performance under challenging grid conditions.
Comprehensive Certification
All models comply with IEC 61869, IEEE C57.13, GB/T 20840, and have passed KEMA, CE, and type tests, ensuring global project acceptance.
Customizable & Fast Delivery
ZHIMING offers tailored ratios, number of cores (for metering, protection, or dual purposes), and enclosures (indoor/outdoor, bushing or freestanding) with typical lead time of 25–35 days.
Preguntas frecuentes
Can a High Voltage Current/Voltage Transformer be used for both metering and protection?
Yes, ZHIMING designs dual-core transformers: one core with high accuracy (Class 0.2) for billing, another with higher saturation point (Class 5P/10P) for relay protection.
How do you prevent ferroresonance in voltage transformers?
ZHIMING adds damping windings and uses anti-ferroresonance core materials. We also provide ferroresonance suppression resistors upon request.
What is the standard secondary burden for current transformers?
Typically 5VA, 10VA, 15VA, or 30VA at rated current of 5A or 1A. ZHIMING confirms burden with user before manufacturing.
Are your transformers suitable for GIS (Gas Insulated Switchgear)?
Absolutely. We produce both AIS (air-insulated) and GIS-compatible Transformador de corriente y tensión de alta tensión units with SF6 gas insulation as needed.
What tests do you perform before delivery?
Routine tests (ratio, polarity, insulation resistance, power factor, partial discharge) and type tests (lightning impulse, temperature rise, short-time current) per IEC standards.
