Capacitor Voltage Transformer (72-550 kV)

POLIPAR Capacitive voltage transformers isolate the measuring instruments, meter, relays, protections, etc., from the high voltage power circuit and provide a scaled replica of the voltage in the HV line

POLIPAR H-CVT Series Capacitor Voltage Transformer  (72-550 kV)

"long term performance and reliability"

Capacitive voltage transformers are used to convert high transmission line voltage (up to 1200kV) to standardized low and easily measurable values, which will be used for metering, protection and control of the high voltage system. As such, the need for accurate and reliable voltage transformation is essential.


POLIPAR Capacitor Voltage Transformer is designed for revenue metering and protection in high voltage networks.
It is of single-phase design and intended for connection between phase and ground in networks with insulated or direct-grounded neutral points. The high quality, state of the art, automated manufacturing of the capacitor elements provides consistent quality to ensure long term reliability and performance. Due to the optimized proportions of the mixed dielectric, the capacitor elements are subject to low electrical stress with high stability under extreme temperature variations.

POLIPAR Capacitor Voltage Transformer is available from 72 kV up to 550 kV. It can withstand a wide range of shifting conditions including polar and desert climates.


  • Revenue metering
  • Protective relaying
  • System control and indication of power flow
  • Power line carrier transmission

Why POLIPAR Capacitor Voltage Transformer

  • Reliable
    • The low voltage stresses within the capacitor elements ensure a safe and reliable product. 
    • POLIPAR provides most efficient ferroresonance damping systems available in the market. POLIPAR´s damping technology guarantees a safe and stable elimination of ferroresonance at all frequencies and voltages up to rated voltage factor.
  • Accurate
    • Good accuracy under all service conditions, independent of variations in temperature, frequency, voltage and burden.
    • Mixed dielectric (polypropylene and paper) in unique proportions, which is far more stable to temperature variations than other mixed dielectrics, and gives the TRANSFORMERS superior accuracy stability.
  • Flexible
    • POLIPAR Capacitor Voltage Transformer is designed and adjusted at factory for the burden and accuracy class  according to specifications.
    • POLIPAR's wide experience and expertise helps find an optimum solution.
