Fluke 5592576 FLUKE-393FC Clamp meter with solar irradiance, CAT III 1500V

The Fluke 393 FC real effective current clamp with measurement category CAT III 1,500 V was developed for technicians who work in high voltage DC environments: PV systems, wind energy, electrical railways and uninterruptible power supply for data center. It measures up to 1,500 V DC, 1,000 V AC, and up to 999.9 A DC/AC using the clamp.

The accompanying flexible current sensor iFlex extends AC measurements up to 2,500 A. The measuring device has a slim wrench, which enables you to access cables in narrow connection boxes. The measuring leads were developed for work up to 1500 V DC and are specified in accordance with CAT III 1,500 V. The Fluke IRR1-SOL irradiation measurement device was developed to simplify the installation, start-up and troubleshooting of photovoltaic systems and to enable the measurement of solar radiation, temperature, inclination and alignment with a single handheld device. The IRR1-SOL can be used anywhere thanks to its robust, compact design, a protective carrying case and an easy-to-read, high-contrast LCD for reading measurements in direct sunlight.

Thanks to simple operation, instantaneous measurement of the sun radiation and integrated temperature sensor, the requirements of the IEC 62446-1 standards for testing, documenting and maintaining photovoltaic systems are met. In addition, the integrated compass and the inclination sensor permit a quick measurement and documentation of the roof or roof alignment Mounting location as well as slopes and panel inclination during measurement, installation or adjustment of a system. Use the IRR1-SOL for:Planning and measuring photovoltaic systems The solar radiation is determined taking into account the shading in order to determine the expected generation of energy at the respective installation site. It will be in full hours of sunshine Measured, the number of hours per day in which 1000 watts are generated per square meter of the photovoltaic system. Location, time of day, season and weather conditions affect the full Sunshine hours.

To determine the actual solar radiation (W/m²) and shading at the installation site, use the Fluke IRR1-SOL to obtain reference values. Measurements After installation of the system, ensure that it works as intended by measuring the electrical properties and actual output power of the modules. The power of a photovoltaic system is calculated from its current/voltage curve (I-V curve). Use the IRR1-SOL irradiation meter to determine the solar radiation required to calculate the output power I-V curve. Comparison and diagnosis Even if installed correctly, a photovoltaic system may not generate the expected electrical power. To obtain the expected output power, the system must complete the Receive the right amount of energy by radiation in order to generate the DC voltage for feeding into the inverters. .
