Frequency range is 45 hertz to 65 hertz. Impulses of greater than one microsecond can be recorded and the range is 25 to 6,000 volts peak.
Measures leakage current while applying a dc voltage at or above the insulation system's operating level. This measurement aids in determining the insulation system's ability to withstand overvoltages such as lightning strikes and switching surges. Unit is compact and portable, air-insulated, uses no oil, and has a plus or minus 2 percent accuracy. Unit measures current as low as 0.1 microamperes and has a continuously variable test voltage with zero-start safety interlock. Unit provides fast charging of high-capacitance samples. Includes a current guard circuit for highly accurate measurements. An optional strip chart recorder for hard copies is available.
Complete with separate measuring and charging modules. A Kelvin-type, four-wire measurement eliminates errors caused by lead and contact resistances Digital readout with automatic zero. Range: 0 to 6 ohms in 5 ranges. Resolution: 1.0 microhms. Includes a 7-foot (2 meter) helical lead set.
