I am looking for a line analizer with the following specs:

input:

- voltage frequency
- voltage between phase and ground
- phase current
- precision: 1%

output:

- equivalent triphase voltage
- equivalent triphase current
- triphase power factor
- active triphase power
- average active triphase power
- reactive triphase power
- active triphase energy
- reactive triphase energy
- phase voltages and currents

other:

- must display data on a LCR
- must send data to a RS232
- must support powers > 70kW and currents > 100A

Any hint ?

Thank you

I can give a hint: contact Dranetz.  They make a line of power
analyzers.  I don't have a URL or a contact for them handy, but I
rented one of their instruments a number of years ago to do this
kind of measurement and it worked great.

BTW, they are expensive beasts- that's why we rented it.
