Instrument transformer CPB

for outdoor servicesingle-phasecapacitor voltage

World-class CVT for long term performance and reliability Capacitor Voltage Transformer CPB 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. The CPB is available from 72 kV up to 800 kV. It can withstand a wide range of shifting conditions including polar and desert climates. Applications • Revenue metering • Protective relaying • System control and indication of power flow • Power line carrier transmission Why Hitachi ABB Power Grids? • Reliable • The low voltage stresses within the capacitor elements ensure a safe and reliable product. • Hitachi ABB Power Grids provides most efficient ferroresonance damping systems available in the market. Hitachi ABB Power Grids´ damping technology guarantees a safe and stable elimination of ferroresonance at all frequencies and voltages up to rated voltage factor.
