AC Current Calibrators
The Laboratory offers calibrations for AC current calibrators or transconductance amplifiers with output in the range 100 μA to 20 A and 20 Hz to 20 kHz. At power frequencies (45 Hz to 60 Hz), the measuring range can be extended to 100 A. However, the calibrator under test must be capable of driving inductive loads as precision current transformers will be used for the measurements in this extended range.
