Where to record values on VFD Circuit
Where to record values on VFD Circuit
(OP)
Hi there,
I am trying to determine the actual Kw cost of a motor being run via a VFD.
Where is the best place to measure the values I and V as there is differnces on the incoming supply to the load side of the VFD?
Thanks in advance.
Thomas

Measuring V and I won't help much. Nor will measuring kW. Unless it is very constant over time. Cost is energy based and that is kWh.
