Coupled Capacitor Voltage Transformer (CCVT)

 

 

 

Description

This component models a coactively coupled voltage transformer.  The input to the model is the voltage across the capacitors, VP (measured from the system in kV) C1 and C2.  The output is the transformed voltage VS (in Volts).

 

The schematic of the CCVT circuit model is shown below:

NOTE: In terms of the CCVT model, the K and a values referred in Finding Saturation Constants And Indices To Match Magnetising Characteristics, should define the relationship between i and B, not H and B. The values i and H are related by the following equation (where N is the number of turns and is the length of the core):
