The GF3031 Electrical Power Calibrator is a powerful and portable three phase current and voltage source.
All test values are generated absolutely synthetically with a high
degree of accuracy and stability. The source is available in 12 A,
24A or 120 A.
The GF3031 three phase portable Electrical Power Calibrator is a lightweight and portable current and voltage source based on
newest technology and serves for solving this problem by simulating
the required load conditions. Operation is performed by integrated
7“ touch screen or via keyboards.
A high accuracy AC and DC power calibrator suitable for calibrating
watt-meters, power meters, and kW-Hr meters. The instrument is
supplied with virtual control software allowing the user full
control via laptop or PC. Frequency can be set in 0.001Hz steps
from 40 to 70Hz, and phase in 0.01degree steps.
GF3031 is electric AC/DC power and energy calibrator for
calibration of power meters, power transducers, power quality
analysers and generally all kinds of power measuring devices. AC
voltage, current, power and energy functions have calibrated phase
shift in frequency range from 45 Hz to 65Hz with resolution as good
as 0.001 Hz.
