(OP)
In order to verify THD 5% at the power network which is 690V 3 phase, I am going to measure THD. Can you tell me Harmonics Analyzer Manufacture and Model you can recommend and what should be conseration into selection of analyzer ?

RE: Harmonics Spectrum Analyzer

Voltech's PM3000 could connect directly to the system under test: depending on the current level you are measuring you might need to use CTs. It will measure current and voltage THD, and give you harmonic power too.

If you use an isolating transducer with good bandwidth you could use any of the numerous spectrum analysers from the usual manufacturers.

RE: Harmonics Spectrum Analyzer

Try the Fluke 430 Series Three-Phase Power Quality Analyzers.  I haven't used it but we did use the Fluke 41 which was an older single phase version.
