ZG47

Multifunction device for verification of electric safety and mains analysis on single-phase and three-phase installations

ZG47 is the complete and versatile multifunction device developed starting from real installation needs.

In a single device, all functions of the most advanced systems for safety testing (standards CEI 64.8) developed by HT; possibility of carrying out mains analyses, THREE-PHASE or SINGLE-PHASE (voltages, currents, powers, power factor, energies, etc.), voltage/current harmonic analysis (up to the 49th) and an analysis of the anomalies on power supply voltages (dips, peaks). The device has a whole variety of functions and can be used with external feelers for measuring environmental parameters such as temperature/humidity of air, illuminance (Lux) further to measuring leakage currents, Loop/Line impedance and calculating the assumed short-circuit current with high resolution (0.1mOhm) in TN systems with the use of the optional accessory IMP57. Cutting-edge management of measurement with indication, at the end of each safety test, of compliance or non-compliance with requirements with simple symbols OK or NOT OK.
