What are Current Transformers used for?
Current Transformers are used to convert high primary currents into lower secondary currents suitable for measurement instruments and protective relays.
How do accuracy classes affect Current Transformer selection?
Accuracy classes indicate measurement precision or protection performance. Metering classes such as 0.2 and 0.5 are used for energy measurement, while classes like 10P10 are used for protection circuits.
Which primary rated current should be selected?
Primary rated current should match the nominal current of the monitored circuit, with options ranging from 5 A to 1000 A depending on the application.
How do thermocurrent and dynamic current ratings relate to operation?
1 second thermocurrent defines short-duration thermal withstand capability, while dynamic current indicates the mechanical withstand during fault conditions.
Where are Current Transformers typically installed?
Current Transformers are commonly installed in switchgear, control panels, and power distribution systems for monitoring and protection purposes.
