The National Institute of Standards and Technology (NIST) calibration service for voltage transformers and high-voltage capacitors is described. The service for voltage transformers provides measurements of ratio correction factors and phase angles at primary voltages up to 170 kV and secondary voltages as low as 10 V at 60 Hz.
Selection and calibration of capacitors for use as Standards is a challenging task, especially since the accuracies required, depening on the application, can be very demanding for the test gear as well as for the secondary- and working-standards used.
The calibration resources for capacitance at low voltages (≤ 100 V) covers the interval 100 fF – 1 mF. The most commonly used method for calibration of capacitance standards in the interval 1 nF – 10 μF is substitution measurements where the object is compared to a known standard with the same nominal value.
Calibrations of high voltage capacitors can be performed up to 300 kV (for more information see the National Laboratory for high voltage and high currents) Other types of measurements can also be performed, for example, measurements of temperature coefficients.
2. Capacitance Calibration The precision measurement of capacitors for the purpose of calibration is generally based on a national primary standard of high accuracy, secondary/working Standards derived from it, and a capacitance- (or LCR-) meter used for the measurement (i.e. calibration) of the devices under test (DUT).
Calibrations at frequencies from 50–400 Hz are available over a more limited voltage range. The service for high-voltage capacitors provides measurements of capacitance and dissipation factor at applied voltages ranging from 100 V to 170 kV at 60 Hz depending on the nominal capacitance.
