Hi
We ( a university) are looking to improve our data capture capability for 3 phase power. Especially important is high speed capture.
We would like to measure 3 phase at up to 100kVA.
Looking at transient response, harmonics, voltage, current, phase, efficiency, power.
Hopefully with some sort of api to log and display stuff.
It doesn't need to be portable as it would normally sit in the same lab but would need to be re-plugged into different parts of the system.
currently we use
https://www.keysight.com/us/en/product/PA2203A/integravision-power-analyzer-4-channels-3-phase-ac.htmlwhich are very good, but still have quite a few issues. Including the screen update rate ( would you believe).
One option i have found is
https://dewesoft.com/products/sirius-xhs which provides 5 MHz bandwidth,15 MS/s, 16 bit. This would be enough for us. 1x HV for voltage, 1 x LV for current, we have the current transducers set up. They are time-synched too.
XHS-HV: Highly isolated CATII 1000V amplifier. Measure in a range of 20 V to 2000 V peak directly. 5 MHz bandwidth. 0.03% accuracy. This amplifier is perfect for the direct connection of high-voltage signals.
XHS-LV: Highly isolated voltage input amplifier. Measure in a range of 0.05 V to 100V. 5 MHz bandwidth. 0.03% accuracy. It offers sensor excitation. This amplifier is perfect for a direct connection of low voltage signals and current transducers.
Does anyone have any opinions of or experience with Dewesoft equipment and especially software that they could tell me about?
Does anyone have any other ideas for something suitable?
We're not afraid "roll our own" but we cant compete with Dewesoft's specs.
