The Model 2100B is designed to generate voltages up to 600V and currents to 100A at any power factor from zero lag though unity, to zero lead. Completely automated, the 2100B is ideal for calibrating wattmeters, energy meters, watt-hour meters, watt transducers and VA measurements to <30 PPM.

Traceability is provided through a built-in standard resistor for in-phase measurements and a standard capacitor for quadrature measurements. The system is also capable of calibrating its own resistance standard directly against an external standard. A controller and software are used to control the units together using an IEEE488 interface. The system is supplied in a 1.8-meter equipment rack on castors for mobility. The rack is equipped with a pullout tray for placing the unit under test (UUT). All connections to the UUT are made from the front panel of the system.

The system is comprised of a Power Comparator (2000A), a 10 mA in phase Quadrature Current Source (2002), Transconductance Amplifier (2701A), an Auto-Ranging Current Transformer (2003A), a Detector Amplifier (2001A), 2501A AC Precision Divider. Several wattmeters, DVM’s and AC/DC Transfer Stan time.

The 2100B Reference Power Calibration System is fully automated and programmable primary standard for AC power measurements. It can be used for calibrating both active and reactive power and energy meters under sinusoidal conditions.

The resistor, capacitor and high voltage divider are supplied with calibration reports. The system, using model 2000A AC Comparator and 2001 Detector, is capable of calibrating the standard resistor against external standards to better than 3 ppm uncertainty. An external resistor, the model 7050, 12K Ohm AC Standard Resistor, may be purchased and sent out for calibration periodically as the reference standard.

Software menus allow for changing voltages, currents, power factors and a number of readings easily. The MEAN, SIGMA, STD. DEVIATION and VARIANCE are calculated and displayed on the calibration report. The 2100B system includes the model 2501A AC Precision Divider. The 2501A has ranges of 600, 480, 240 & 120 with uncertainties of less than 10 PPM. The AC/DC Transfer Standard is not exposed to voltages greater than 120V. The accuracy of the 2100B is based on uncertainties associated to measuring R and C and the input voltage via an automated AC/DC Transfer Standard and the uncertainty associated with the 2501A High Voltage Divider. The resistor and capacitor are included in the model 2002 Current source are supplied with an NRCC calibration report. Calibration of the resistor and capacitor are performed at the test voltage of 120V and frequencies of 50, 60 and 400 Hz.
