The Megger S1-552 high-current 5 kV insulation resistance tester is designed to test high-voltage electrical equipment, assisting electricians with the testing and maintenance of high-voltage electrical equipment.
The instrument features a digital/analog backlit display, variable test voltage from 50 to 5000 V, up to 15 TO impedance measurement, noise rejection of 2 mA RMS at 200 V to take effective readings in high-noise environments such as high-voltage substations and switchyards and automatic IR, PI, DAR, SV and DD tests
The mains or battery-powered instrument drives 5 mA of short-circuit current, which allows for faster charging and testing of large capacitive and inductive loads. It includes RS232 and USB interfaces to download results to a PC.
