Analyze power on all sides

摘要

To see how a power source or load affects-and is affected by-harmonics and noise, you need to see pow« waveforms as they enter and exit a device. Yokogawa's WT1800 power analyzer lets you check power waveforms at up to six locations through six modules that can be simultaneously inserted into the back of the instrument The six channels let you simultaneously analyze voltage, current, and power on both the input and output of a device that runs on three-phase power, and you can use the data to calculate efficiency. Each measurement module samples at 2 Msamples/s with 16-bit resolution. Input voltage ranges from 1.5 V to 1000 V through direct inputs.
