I am trying to determine the parameters of various induction machines.
I am wondering if there are any measurment tests (such as with a meter clamp) I can do to determine HP, KV, FLA, and LRA?

I am trying from my point of view to help,asking question is ok.
you should help If you want. What I'm trying to say you can read
a chapter is a book,It would help If you had a picture in your mind
what Is happening associated with real life experience like car radio
and c.d. player. Remember to keep your respect. You notice a lot
motor tech's did not jump on this post,there are strange ways to
determine h.p. like useing buckets of sand and pulleys as a way
to determine h.p. load .

You will not know your motors voltage rating, unless it's either stamped on the ID tag, or you have that info from the winder/manufacturer. Code requires an ID tag.

HP is similar. If you knew the voltage, %speed regulation, and power factor, you could do a lines measurement / calculation to come up with a close hp.

FLA and LRA can be done with an ammeter. LRA can be around 600% FLA.
