Analysis and Suppression of the Coupling Capacitor Voltage Transformer Ferroresonance Phenomenon
This paper provides a detailed core model for the step-down transformer (SDT) of the coupling capacitor voltage transformer (CCVT) to investigate the CCVT transients and ferroresonance behavior. The core model represents hysteresis symmetric and asymmetric minor loops, remnant flux, and the eddy current effects. Based on the …
Coupling Capacitor Voltage Transformers (CCVTs)
Essentially a CVD is composed of two capacitors, C1 and C2, although in practice C1 either may be made up of a single capacitor stack or several capacitor stacks connected in series. When there are several stacks, these are designated C1-1, C1-2, etc., or in infrequent cases, B1, B2, etc.
