Multivalue High Voltage Loss Angle Standard

The standard of the loss angle tangent (D) is intended for calibration of capacitance bridges at the voltage 1-10 kV and frequency 50 Hz. A high repeatability of the D values is obtained due to special design, and the usage of small-size ceramic capacitors makes the standard portable. The expanded uncertainty of the output parameters of the standard is (1-2)middot10^-5+0,001D for the loss angle tangent and 0,1 % (k=2) for the capacitance
