Applied Power Electronics Conference 2025 (APEC 2025)

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 Yokogawa CW500 is a portable power analyzer that logs transient power phenomena in addition to measuring single to three phase power.
