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

Multifunction device for verification of electric safety and mains analysis on single-phase and three-phase installations.
GSC57F is the first big multifunction device developed by HT! In a single device, all functions of the most advanced systems for safety testing; 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); continuity test with test current 10A.
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 shortcircuit 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.
