In some power measurement applications, the current in the device under test is higher than what can be applied directly to the power analyzer current input terminals. Current transformers are used to step down high AC and DC currents to a lower level that can be measured directly by the power analyzer. These systems safely step down currents while preserving the highest accuracy.
The CT family of Yokogawa Test&Measurement current transformers is rated for both AC and DC currents. The following table highlights some of the common specifications to help select the best option for different power measurement application needs.
