current transformer in detail

Question

Accepted Answer

A current transformer is a device used to measure or monitor electrical currents in power systems.

It is a type of instrument transformer that steps down high currents to a lower, more manageable level.
The primary winding of the current transformer is connected in series with the circuit carrying the current to be measured.
The secondary winding of the current transformer is connected to a measuring or monitoring device.
The secondary current is proportional to the primary current and is typically scaled down by a ratio of 1000:1 or 100:1.
Current transformers are commonly used in power systems for protection, metering, and control purposes.
They provide isolation between the high voltage primary circuit and the low voltage secondary circuit.
Current transformers are designed to accurately reproduce the waveform and magnitude of the primary current.
They have high accuracy and are capable of measuring both AC and DC currents.
Current transformers are typically labeled with their primary and secondary current ratings.
Examples of current transformer applications include energy management systems, power quality monitoring, and fault detection.
