New high-voltage insulation resistance testers deliver accuracy and speed

Fluke has announced two portable and lightweight (1.3kg) Insulation Resistance Testers for fast, accurate and reliable testing up to 2500V (DC).

The high-voltage 1535 and 1537 Insulation Resistance Testers are excellent for industrial electricians, maintenance technicians, electrical engineers and field service engineers looking to streamline frontline troubleshooting and enhance productivity. Whether used on the factory floor or in the field at a solar PV installation, for maintenance work on such equipment as motors, transformers or power cabinets, the insulation testers supply equally rapid and stable resistance measurements and allow users to cover greater workloads with a single tool.

Completing the tester range the testers can take up to 6500 measurements at 250V or 1300 measurements at 2500V with one set of batteries, providing the user complete control. For greater flexibility, test voltages are user selectable and adjustable, and a ramp function is available, which is excellent for industrial or solar PV applications. Resistance measurements can also be taken up to 500GOhm, whether working on small circuits or high-voltage systems, while the 1537 Insulation Resistance Tester allows measurements to be stored for later review or PC transfer using the Fluke software provided.

These testers are user-friendly with intuitive user interfaces. The Fluke 1537 has a high short circuit current of up to 5mA and the testers have enhanced safety rating through CAT IV 600V and built-in voltage alarm function. At the same time, the units comply with the standard series IEC 61557 and IEC 61010 for safety and IEC 61326-1 for electromagnetic compatibility. Furthermore, Automatic PI and DAR calculation means the influence of environmental factors on insulation performance can be minimised without further set-up.

Says Hans-Dieter Schuessele, application and technology expert and standardisation manager EMEA, Fluke: “With these high-voltage 1535 and 1537 Insulation Resistance Testers, operators now only need to use a single device to test a wider range of applications than before in the knowledge that they will always get rapid, stable and reliable results. The new testers put the user in control when carrying out vital maintenance work, whether in industrial and solar PV applications, and help to improve the productivity of electricians and contractors through a range of valuable features.”
