GSC53N Multifunction Tester and Three-phase Power Analyzer GSC53N is strong evolution equipment developed by HT ITALIA to perform complete test and verify on electrical installations according to the most common safety standards (IEC 61557, VDE 0100 and BS7671) and for power quality analysis on general electric networks. This meter, sure, with high accuracy, dedicated to each proof technician, is a very user-friendly instrument thanks to the followed new integrated features: - Setting up to 5 predefined recordings on power quality (EN50160, Voltage Anomalies, Harmonics, Start-up and Power & Energies) for a easier and rapid analysis of the most common situation on plants. - Use of flexible clamp transducers with integrated control logic. In this way disappear the problem of replace batteries of power adaptor typical of transducers with external control logic. GSC53N model can perform LINE/LOOP Impedance and prospective short circuit current measurements with high resolution (0.1 mΩ) with use of IMP57 optional accessory. In this way is possible realize important measures strictly nearly to power transformer. Due to our policy of continual product development we reserve the right to amend the specifications of all mentioned products without notice.
