GSC57 / GSC53N / ZG47 : INTEGRATED INSTRUMENTS FOR ELECTRIC TESTS, MAINS ANALYSES ON SINGLE-PHASE AND THREE-PHASE SYSTEMS AND ENVIRONMENTAL PARAMETER MEASUREMENTS
GSC53N, GSC57 and ZG47 are strong evolution equipment designed to perform complete test, to verify electrical installations according to the most common safety standards (IEC 61557, VDE 0100, BS7671, etc.) and to carry out power quality analysis on general electric networks. Flexibility of these meters permits their use by installers, technicians, engineers and testers of electrical plants and equipment. GSC53N, GSC57 and ZG47 measure, among the other things, a fault Loop Impedance with high resolution (0.1 mOhm) near power transformers thanks to the use of IMP57 as optional accessory. As power quality analysers, the instrument can record all values of electrical parameters (Voltage, Current, Power, Power Factor, Energy, etc.), perform harmonic analysis of voltage and current (up to 49-th order) and permit voltage quality analysis according to EN50160 standards. With optional probes, GSC53N, GSC57 and ZG47 can also perform measures and recordings of environmental parameters as temperature, humidity, illumination (Lux) and leakage current which are very important for troubleshooting problem of RCDs wrong tripping. Each measure can be stored inside instrument memory, recalled on instrument display and transferred to PC using the management software to create a professional relation which will improve the work quality.
