D100

Insulation Diagnostic System

Insulation Diagnostic System D100 measures the capacitance and dissipation/power factor, excitation current, transformer turns ratio with the test voltage up to 12 kV
For a more detailed analysis the device makes it possible to obtain the dependence dissipation/power factor on frequency (frequency sweep) and voltage (tip-up)
