| Transformer-Rated Site Tester
Minimize the risk of revenue loss and improve productivity and profitability in the field
With the ST-3/XT3, field technician can accurately test CT/PT Transformer-Rated Site by performing a power quality test, primary/secondary analysis, CT burden and admittance test in mere minutes and provide traceable reports with critical data insights needed to detect problems at the source and maintain optimal metering equipment.
- Control the ST-3/XT3 wireless CT-rated site analyser with the Probewell Connect 2.0 app via the built-in private WiFi network
Uncompromised accuracy:
- 3 built-in current sensors up to 20 A
- Typical accuracy of 0.05%
- Maximum accuracy of 0.1%
SKU: XT3
Big technological leaps come in small packages…
Weight: 4.5 lb. | Size: 6.9″ X 7.4″
ST-3/XT3 | Description
Available tests
Power Quality
Real-Time Waveform
Phasors
Total Harmonic Distortion
Primary/Secondary Analysis
CT Burden
Admittance
Speed up the process without ever compromising safety
The ST-3/XT3 is a sophisticated yet rugged device that is easy to use and is controlled remotely thanks to the integrated WiFi and the Probewell Connect 2.0 application. The application is offered free of charge and can be installed on your laptop, tablet or cell phone.
Connecting the ST-3/XT3 to the meter base installation takes less than a minute and does not require any special tools other than adjusting the form selector and configuring the removable twist tabs at the back of the device.
Above all, the Probewell Connect 2.0 user interface gives you access to a full range of tests to measure current transformer accuracy and securely perform routine inspections of the installations performances, such as:
- The power quality analysis which allows you to visualize live data of the harmonic distortion in power quality or waveform distortion in power quality as well as checking the phase angles of the 3-phase vector diagram.
- Testing the CT ratio or analyzing the transformer primary and secondary current.
- Testing the burden of potential transformers.
- Testing admittance.
