Accurate performance for the calibration laboratory
Until now, many engineers and technicians have been testing three-phase devices with a single-phase series-parallel technique, because the cost of available three-phase sources with acceptable accuracies has put true polyphase testing out of reach. With the GF302D1, these professionals can now afford three-phase performance, accuracy, and ease of use. More importantly, they can now test multi-phase meters in conditions that reflect their actual usage.
Along with providing three independent phases of precise voltage and current, the GF302D1 also sources power quality phenomena, including harmonics, interharmonics, flicker (modulation) and dip/swell variations.
The GF302D1 includes measurement capabilities for dc voltage, dc current and frequency for measuring outputs from power and energy transducers.
As a single instrument, the GF302D1 is easier to transport and takes up less space on the bench or cart than multi-piece units. The GF302D1 delivers all of this functionality with a graphical user interface that makes it remarkably easy to learn and use.
Versatile and convenient functionality for the manufacturing floor
The GF302D1 is a single-instrument solution for single or multi-phase sourcing applications, making it ideal for many applications within electronics manufacturing companies and electric utility meter shops.
Now you can efficiently conduct final verification of power transducers, current transformers, energy meters, and revenue meters using true multi-phase testing methods. Test and calibrate single and multi-phase power meters, power quality analyzers and energy meters.
Put the GF302D1 on a cart and wheel it easily around the factory floor to test workload in situ. The graphical user interface makes setup a snap; all three phases are readily available for verification testing.
