CP is intended for phase to ground connection in power networks with insulated or grounded neutral points.
Reliable
The low voltage stress within the capacitor elements ensure a safe and reliable product with a long life.
CP is equipped with one of the most efficient ferroresonance damping systems available on the market. ABB´s damping technology guarantees a safe and stable elimination of ferroresonance at all frequencies and voltages up to rated voltage factor.
During the last 25 years more than 25,000 units have been installed in more than 100 countries all over the world, from desert to arctic climates.
Accurate
You can expect good accuracy under all service conditions, independent of variations in temperature, frequency, voltage and burden.
ABB uses a mixed dielectric (polypropylene and paper) in unique proportions, which is far more stable to temperature variations than other mixed dielectrics and gives the CP superior accuracy stability.
Flexible
CPA and CPB are tailor made according to your specifications.
ABB design and adjusts CP at factory for the burden and accuracy class according to your specification. You can however optimize the accuracy of your CVT for a given burden to less than 0,025% ratio error by using the adjustment windings accessible in the secondary terminal box.
