measuring power and current

[Boopster]

Hi,

 I have a Crio 9022 and the NI 9227 and NI 9225.  I have Labview Development version, I do not have the FPGA nor the Electrical Power Suite.  Can I still measure power from my system?

Hi,

If you want to utilize 9225/9227 to acquire the signals, you must insert them into one cRIO or cDAQ chassis. If you have only one 9022 controller, I am afraid you cannot use the 9225/9227.  So firstly, you need to setup a full set of cRIO system.

For simple power measurement, the FPGA-based processing is not required. You could install Eletrical Power Suite (base version), and there is a palette "Basic Measurement". It is free and doesn't depend on FPGA. It includes the basic measurement VI for power (active power, inactive power, etc).

Hi,

You can use a single 9022 since it should have a4 or 8 slot chassis.

You will need some level of FPGA since you need to capture the data as waveforms and the scan engine will but be fast enough.
