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.

The invisible threat….now you can see
Partial Discharge is a very serious issue that you are scanning for every day. Whether you are scanning insulators, transformers, switch gears or high-voltage powerlines you need to be sure that you spot a problem quickly and early. Partial discharge that goes unchecked can cause blackouts, fires, explosions, or death from arc flashes. In addition to the danger that this can pose to the environment and human lives it also has a very steep price tag. Having equipment go down can cost millions of dollars per hour of downtime, and studies have shown that a single data centre outage could cost $8,851 per minute. On top of this, the Department of Energy estimated that outages are costing the US economy $150 billion annually.
Key areas to scan for PD
• Insulators
• Transformers
• High voltage powerlines
• Switch gears
• Arrestors
• Busbars
• High voltage coils
• Breakers
• Capacitors

Do it fast, Do it safe
The ii910 is the all-in-one tool you have been looking for when it comes to all of your leak and PD issues. Everything you need is right at your fingertips. Quickly scan the area or environment and get all the pictures/videos you need with the simple one-button capture and large 7” touchscreen LCD. No additional tools or equipment are needed. Without cumbersome secondary cables or devices needed, you have full mobility and greater flexibility to swap between detecting of the leak/PD and fixing the leak/PD.

Since May 20, 1875, when representatives of 17 nations signed the Metre Convention, the world has agreed upon one, uniform measurement system–celebrated through World Metrology Day. Over the years this system has been adjusted and adapted to changes in technology. Throughout the first three industrial revolutions, metrologists have been able to be more and more precise with their measurements which helps technology continue to advance. The digital era, or the fourth industrial revolution, is no different. Metrology plays a huge role in IoT, technology, and digitization.

Fluke Chief Corporate Metrologist Jeff Gust, Metrologist Nicholas Mason, and Software Metrologist Michael Brown explain how metrology is playing a huge role in the digital era and will continue to help advance technology in all industries.

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.

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.

Get the job done right the first time with Fluke TiS60+ Infrared Camera
Boost your team’s performance with 320 x 240 resolution and outstanding 45mK thermal sensitivity. Its easy-to-use fixed focus means you can simply just point and shoot, and the TiS60+ will do the rest.

Fluke Pro, Jason Axelson explains why early identification of battery failure helps keep your assets as well as your company up and running.

Use a battery tester to measure voltage, internal resistance, and strap resistance to find indications of early-stage battery failure or installation problems.

Key measurements – Internal battery resistance, dc and ac voltage, dc and ac current, ripple voltage, frequency, and temperature.

Sequence measurement mode – Automatic or manual sequence testing of battery strings with automatic measurement storage including voltage, resistance, and temperature (with BTL21 intelligent test probe), eliminating the need to press a button each time measurement needs to be saved.

Comprehensive logging – All measured values are automatically captured during testing and can be reviewed on the instrument before downloading for on-the-go analysis.

Shaun from Fluke educates us why an insulation tester is a crucial tool to have. He elaborates on the benefits yield by the insulation meter.

Check out our insulation testers and see what they do: https://comtest.co.za/Online-Store/Ca...
-----------------------------------------------------------
Why do you need an insulation tester?
The insulation tester is designed to check the integrity of conductors wires or check the insulation value of motor/compressor windings. We check if there is a breakdown in there that might cause malfunctioning. Insulation tester is helpful for a preventive maintenance plan (PMP) it allows you to do a streamlined test and baseline test.

hether you’re surveying, installing, executing maintenance or checking the performance of solar panels or a photovoltaic system, the Fluke irradiance meter takes 4 critical measurements needed.

With the Fluke irradiance meter, you can make instantaneous measurements to determine the watt per square meter solar irradiation. Measure the ambient temperature at the panel easier and faster than ever.

The Fluke IRR1-SOL is the only irradiance meter that can take the temperature without needing an external probe. This is enabled by innovative Fluke technology which embeds an integrated conductive temperature sensor in the meter. Temperature can also be measured with increased accuracy with the external temperature probe.

+ A built-in compass enables you to measure and document roof or site orientation.

+ An inclination sensor lets you know the solar panel tilt when surveying, installing or adjusting the installation.

+ The Fluke irradiance meter is robust, rugged, compact, and ergonomically designed so it fits comfortably in your hand.

+ The high contrast LCD and large, readable numbers make the screen easy to see even in bright sunlight.

+ It comes with a convenient carry case with a shoulder strap.
