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.

Current probes allow you to measure DC or AC current.  Yokogawa's selection of current probes allow measurements ranges up to 500 ARMS and bandwidths up to 100MHz.

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

Yokogawa data acquisition systems give you the most flexibility and power to measure, display, store, and even actuate any number of physical or electrical phenomena.

A compact, battery-powered, touch screen instrument you can take into the field featuring the deep measurement and recording capabilities you need in the lab.

The Yokogawa Test&Measurement DL950 ScopeCorder captures and analyzes a wide variety of electrical, physical sensor signals, and serial buses. It offers a unique combination of high sampling rates, for a detailed view and long recording times to monitor trends over time.
