New 7 Phase Power Measurement Mode for the PPA3560!

A new algorithm has been developed for the PPA3500 precision power analyzer which enables 7 phase power measurement utilizing only 6 wattmeters. With the new “7 Phase” mode the engineer is able to obtain true 3 phase measurements when connected in a 3 Phase 2 Wattmeter wiring configuration. Previously, only SUM parameters were able to be determined when connected in a 3 phase 2 wattmeter configuration – these restrictions no longer apply.
