What is one of the key advantages of using current transformers?

Using current transformers offers significant advantages, one of which is providing isolation from high voltage. This feature is crucial in electrical systems as it enhances safety and protects sensitive equipment. Current transformers are designed to step down high currents to a more manageable level that can be safely monitored and controlled.

When a current transformer is employed, it allows for the measurement of high currents without direct electrical connection to the electrical system carrying the high voltage. This isolation minimizes the risk of electrical shock or damage due to high voltages while allowing for accurate current measurement. Furthermore, this isolation aids in protecting the control and measurement devices connected to the transformer from the hazards associated with high voltages present in the primary circuit.
