How Does It Work?
Embedded within the ST-3/XT3, is a high performance multiphase energy metering circuitry.
Thereby allowing a full RMS and line cycle measurement of both secondary (at the meter base) and primary (with accessories) currents and voltages.
In short, the ST3/XT3 offers elaborate test modes that can leverage such measurements to assess the Power Quality on the secondary side or perform complete transformer ratio analysis
Lightning Quick Setup!
The Form selector switch and removable twist tabs enable a toolless configuration to match any transformer rated meter base form.
Consequently, you will be able to test sites with any of these CT rated meter forms:
Single-Phase: 3S and 4S
Polyphase: 5S, 6S, 8S, 9S, 35S and 45S
Fitzall™: Classe TC
Setting-up your test has never been easier; you’ll be testing in no time.
Integrated WiFi Technology
No network, not a problem!
In other word, its robustness, compact size and ease of operation make it an indispensable tool for testing sites in remote areas.
Leverage crucial digital insights!
