Phasor Measurement Unit Calibration Service Improving Accuracy of Power Grid Measurements

NIST is now providing a service for Phasor Measurement Units (PMUs), to the IEEE Synchrophasor Standard C37.118-2005 performance requirements as a Special Test 56230S.

Thermal Resistance Measurements of Calibration Transfer Specimens

Thermal resistance measurements are provided by the NIST 1016 mm Guarded-Hot-Plate Laboratory in air at site pressure (100 kPa ± 20 kPa). Services at ambient pressures outside these limits or with other gases are not provided. These measurements are performed once a year. Services 36110C, 36120C, 36130C, 36140C, 36150C and 36199S.
