Potential transformers and coupling capacitor voltage transformers (CCVT''s) have been used successfully for providing voltage to the inputs of meters and relays since the 1960''s. At voltage levels above 138kV ... Another factor in selection of a CVT is the type of ferroresonant suppression system used. The transient
capacitors and the transformer, the commutation transient is too short to affect the selection of these components. Thus a model without the junction capacitor is used to describe the converter. 4.1. Bus capacitor selection The key parameters for the capacitor selection are capacitance, voltage and rms current. All of these can be
Both p-type and n-type silicon will conduct electricity just like any conductor; however, if a piece of silicon is doped p-type in one section and n-type in an adjacent section, current will flow in only one direction across the junction between the two regions..
