The world’s only CAT III 1500 V current clamp, Fluke 393FC with iFlex is designed for technicians who work in dc environments up to 1500V.

The Fluke 393 FC features:
- IP54 rating for dust and water makes it ideal for work outdoors on solar arrays and wind power systems.
- DC power measurement, showing readings in kVA.
- Audio and Visual Polarity to ensure photovoltaic panels are properly - installed with the help of an audio beep and a light to indicate correct polarity.
- Visual Continuity provides a bright green indicator light in the display for working in dark and noisy environments.
- Logging, sharing and reporting of test results via Fluke Connect software.

Fluke was founded by an engineer, so they believe it's important to celebrate the technology and innovations these individuals bring into our everyday lives.

Engineers have always played a leading role in our lives, from the invention of the wheel to Mars exploration rovers. That’s why we're taking March 4th to celebrate World Engineering Day. Highlighting the engineers at Fluke and promoting engineering as a career and inspiring us to change the world for the better.

The Fluke 500 Series Battery Analyser is the ideal test tool for maintenance, troubleshooting and performance testing of individual stationary batteries and battery banks used in critical battery backup applications.

Some key features of the Fluke 500 Series include:
• Battery Voltage – During the internal resistance test, Fluke Battery Analysers also measure the voltage of the battery under test
• Discharge Volts – The Discharge mode collects the voltage of each battery multiple times at a user-defined interval during a discharge or load test. Users can calculate the time a battery takes to drop to the cut-off voltage and use this time to determine the capacity loss of the battery
• Ripple Voltage Test – Measures unwanted residual ac component of the rectified voltage in dc charging and inverter circuits. Allows users to test ac components in dc charging circuits and find one of the root causes of battery deterioration
• Meter and Sequence Modes – The Meter mode is used for quick tests or troubleshooting. In this mode, you can save and read the readings in a measurement or time sequence. The Sequence mode is for maintenance tasks with multiple power systems and battery strings. Before a task starts, users can configure a profile for the task for data management and report generation
•Threshold and Warning – Users can configure a maximum of 10 sets of thresholds and receive a Pass/ Warning/ Fail indication after each measurement.
• Intercell Strap Resistance Test and Data Management – Measures the resistance of the intercell connection between batteries in a string. Once the measurements are completed Fluke Battery Management Software version 1.0.69 can now report the strap resistance for a battery string or historical data over time and much more.

Solar I-V curve tracing: what it is, what it reveals, and why it's important for PV arrays.

This full interview with Stephen San Juan, a solar training and renewable energy safety expert, gets into the subject of I-V curve tracing. He explains what an I-V curve tracing is, what it reveals about a PV array, and why regular testing is so important, especially for large PV systems.
