Yokogawa Test & Measurement Releases CT1000S AC/DC Split Core Current Sensor

Yokogawa Test & Measurement Corporation announces the release of the CT1000S AC/DC split core current sensor. The CT1000S combines the accuracy of Yokogawa’s conventional current sensors with the convenience of a clamp design, and features a high common mode rejection ratio (CMRR) and excellent frequency characteristics, even at measurement frequencies of 10 kHz or higher. As such, the CT1000S is an ideal solution for test applications that require wide-bandwidth, high-current measurement.

The CT1000S is able to measure AC and DC currents of up to 1000A and has a wide DC to 300 kHz measurement frequency range. A high CMRR and excellent linearity of frequency characteristics ensure precise power measurement in high-frequency applications that have dramatic changes in current levels and thus require a wide dynamic range, while high resistance to electromagnetic noise ensures more accurate readings.

For tasks such as the evaluation of inverter carrier fundamental frequency components and reactor losses that necessitate wide bandwidths and the measurement of large currents, the CT1000S can be paired with Yokogawa power analyzers and waveform measurement instruments. Thanks to a clamp design that eliminates the need for the disconnection of wires, the CT1000S current sensor is easy to set and remove. To ensure stable measurements and enhance reproducibility, the CT1000S sensor unit and cable can be fixed in position. Cable lengths of 3m, 5m, and 10m are available (more info).
