Post by thread:[OT] line analizer

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 Duilio Foschi Irel LLC

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. ------------ Barry King, KA1NLH Engineering Manager NRG Systems "Measuring the Wind's Energy" Hinesburg, Vermont, USA http://www.nrgsystems.com
