Fluke 1735 Three Phase Power LoggerFluke 1735 Three Phase Power Logger The Fluke 1735 Three Phase Power Logger is the idea tool for electrical load studies, energy consumption testing and general power quality logging. The Fluke 1735 logs most critical three phase power parameters plus harmonics and captures voltage events. The Fluke 1735 can log rms voltage, rms current, phase angle, voltage events, voltage and current THD, voltage and current harmonics up to the 50th, active power,
