HEAT INSULATION With class-leading noise rejection of 8 mA - twice that of most comparable instruments - and enhanced software filtering that has four user-selectable options, Megger’ s S1-568 5kV dc insulation resistance tester delivers dependable results in even the most severe of electrical environments, including high-voltage transmission and distribution substations. Not only has the performance of these groundbreaking instruments been exhaustively proven in the laboratory, it has also been convincingly demonstrated in the field. Accurate and consistent results were, for example, obtained in a working 765kV substation where no other insulation tester had been able to operate successfully. Other innovative features include provision for remote control via a fully isolated USB port, which makes the instruments ideally suited for use in production environments, and internal storage for date-and time-stamped results. Stored results can be recalled to the display, downloaded via a Bluetooth wireless link or accessed via the USB port. Megger S1-568 Features Output voltage maximum: 5kV.
