Current Transformer
Manufacturer and Supplier in India
Current Transformers (CTs) are electrical devices that are used to measure the current flowing in a power system. They are typically used in high-voltage and high-power systems, such as those found in industrial and utility applications.
A CT works by inducing a secondary current in a coil of wire that is wrapped around a magnetic core. The primary winding of the CT is connected in series with the conductor carrying the current that needs to be measured, while the secondary winding is connected to a measuring device or instrument.
The amount of current induced in the secondary winding of the CT is proportional to the amount of current flowing through the primary winding. By carefully selecting the turns ratio of the CT, the secondary current can be scaled to an appropriate level for the measuring device or instrument.
CTs are often used in conjunction with protective relays, which are devices that monitor the power system for abnormal conditions and can trigger protective actions, such as tripping a circuit breaker, in order to prevent damage to equipment or ensure the safety of personnel.
