We work on a project where have to measure online values of I, U, PF, etc. Also, we shall induce some disturbance in the system and in that case, we want that a power monitoring device records I, U, f with sampling time 5 or 20 ms (we can trigger the power monitoring device or it can do by itself).
We would like to have access to those recorded file independently of any software. For example, COMTRADE files are fine, but there we do not have logged data for frequency.
Measurement accuracy should be Class 0.2 or better.
What device can you recommend?
You have choice of ION75/650 ION7400 (PM8000) use with PME software.
Access to data recorders are proprietary native software from meter manufacturer is a must except in case of COMTRADE file.
