Megger Enhances S1 Series of Insulation Resistance Testers

Sept. 16, 2008
The new S1 Series of 5-kV and 10-kV insulation resistance testers from Megger are designed specifically to assist the user with the testing and maintenance of high-voltage equipment.

The new S1 Series of 5-kV and 10-kV insulation resistance testers from Megger are designed specifically to assist the user with the testing and maintenance of high-voltage equipment. Each instrument’s control panel is designed in a landscape style that is more familiar and user-friendly.

CAT IV 600 V safety rating allows for safe use in the widest range of applications. The instruments drive 5 mA of short circuit current, which allows for faster charging and testing of large capacitive and inductive loads.

The measurement ranges have been increased significantly for both units. The S1-552/2 and S1-554/2 measurement range has been expanded to 15 TÙ. The S1-1052/2 and S1-1054/2 offer an increased measurement range to 35 TÙ to provide trending values for the best of insulating materials used on the higher capitalized equipment.

The S1-552/2 and S1-554/2 offer variable test voltages of 50V to 1 kV in 10 V steps and 1 kV to 5 kV in 25 V steps. The S1-1052/2 and S1-1054/2 offer 50 V to 1 kV in 10 V step and, 1 kV to 10 kV in 25 V steps.

A large, easy-to-read backlit LCD makes them equally suitable for use in both bright sunlight and poorly lit environments. Information displayed includes resistance, voltage, leakage current, capacitance, battery status and time constant. In addition, the elapsed time is displayed constantly, removing the need for separate timers. They also allow up to three timed measurement positions to be set, which simplifies DAR testing.
