Monitoring analyzer PRA64-EH102-E00 FEMTO PRO D4 ECT

for electrical networks3-phase electrical networksfor single-phase electrical networks

Overview
Single/Three-Phase Energy Analyzer for up to three single-phase lines. Accuracy class 0.5S. Designed for measurement of harmonics and power quality parameters. External ECT current transformers required for current measurement (CTs not included) — example model: PFAE000-09 (100 A). Measures THD and TDD on voltage and current, neutral current, maximum and minimum voltage, maximum current and power, and active energy per phase.

Main features
