The clamp meter is capable of measuring up to 1500 V DC, while conventional instruments are limited to 1000 V DC.
For all these reasons, the Fluke 393 is the ideal choice for the installation and maintenance of large commercial and industrial solar farms. Given the increasing importance of solar power generation in meeting the demand for renewable energy, the new clamp meter is a valuable addition to Fluke's range of instruments for solar applications. Other examples include the Fluke 1577/1587 insulation testers and the Fluke 87V MAX IP67-rated multimeter.
A high level of user safety is guaranteed thanks to its CAT III 1500 V insulation. This solar clamp meter is the only one offering this level of protection for solar installation technicians and engineers. The instrument's insulated test leads are rated CAT III 1500 V, while the instrument itself offers CAT IV 600 V AC protection.
The Fluke 393 clamp meter's IP54 rating makes it suitable for testing solar installations in various climates and weather conditions, protecting it from dust and rain.
Thanks to its ability to measure quickly, easily, and accurately, maintenance technicians won't have to interrupt energy production at solar installations. The challenge they face is solar combiner boxes, which are often small and densely packed, making it difficult to connect instruments for measurements. The Fluke 393 overcomes this challenge with a jaw that is 25% thinner than previous Fluke clamp meter models, making it easier and faster to take measurements in confined spaces.
The jaw is designed to be durable, rugged, and reliable, and meets the stringent CAT III requirements for distances and creepage distances.
The 393 FC is compatible with Fluke Connect, eliminating the need for handwritten notes. Fluke Connect allows maintenance technicians to record values and share them with their team. Up to 65,000 data points can be logged and uploaded.
In addition to voltage and current measurements, the new clamp meter can measure DC power and record the data to improve work efficiency.
Productivity is enhanced by a beep indicating correct polarity of the photovoltaic units, as well as a continuity indicator for easy continuity testing in low-light environments. These instruments also feature a dual-line display for simultaneous measurements.
Hans-Dieter Schuessele of Fluke states: “The new 393 and 393 FC are the world’s first solar clamp meters to offer CAT III safety up to 1500 V, setting a new standard for testing solar installations. They are designed to be extremely safe and easy to use, and are a great help to installers and maintenance personnel, enabling them to quickly bring solar farms online and keep renewable energy production going.”.
