Fluke, manufacturer of electronic test and measurement tools and software for professionals, offers two lightweight, portable insulation resistance testers for fast, accurate and reliable measurements up to 2,500 V.
Fluke's 1535 and 1537 high-voltage insulation resistance testers are aimed at electricians and engineers working in industry, maintenance and on power grids, to simplify emergency troubleshooting and improve productivity. These insulation testers provide fast, stable measurements, and enable more tasks to be carried out with the same tool, whether in a workshop or on the site of a photovoltaic installation, or for the maintenance of motors, transformers or electrical cabinets,
A comprehensive offering
The 1535 and 1537 insulation resistance testers can take up to 6,500 measurements at 250 V or 1,300 to 2,500 V with a single set of batteries, giving the user total control. For added flexibility, test voltages can be selected and set by the user, and a ramp function is provided, ideal for photovoltaic applications, including industrial ones.
Resistance measurements of up to 500 GΩ are possible, from small circuits to high-voltage systems. What's more, the 1537 insulation resistance tester offers the option of storing measurements for later verification or transfer to the PC using the supplied Fluke software.
These two testers - which complete Fluke's offering - benefit from intuitive user interfaces. The Fluke 1537 handles a higher short-circuit current of up to 5 mA, and both testers have extended CAT IV and 600 V safety features, as well as a built-in voltage alarm function. In addition, both units comply with IEC 61557 and IEC 61010 standards for safety, and IEC 61326-1 for electromagnetic compatibility. Finally, calculation of the automatic polarization index (PI) and dielectric absorption ratio (DAR) means that the influence of environmental factors on insulation performance can be minimized without recourse to additional configuration.
According to Hans-Dieter Schuessele, applications and technology expert and EMEA Standards Manager at Fluke: "Thanks to the 1535 and 1537 high-voltage insulation resistance testers, operators only need to use one device to test a wider range of applications, while being guaranteed fast, stable and reliable results. The new testers put the user in control when carrying out vital maintenance work, whether for industrial photovoltaic applications or others, and help to improve the productivity of electricians and companies thanks to a whole range of relevant features."
