The Fluke 1535 and 1537 2,500 V Insulation Resistance Testers are engineered to simplify frontline troubleshooting whether you’re on the factory floor or working in the field at a solar installation. With user selectable test voltages from 250 V to 2,500 V and resistance measurements up to 500 GΩ these testers allow you to cover more workload with a single tool. Equipped with an intuitive user interface, a short circuit current of up to 5 mA and a CAT IV 600 V rating these portable high-voltage insulation testers can deliver rapid and stable resistance measurements no matter where you take them. The 1537 Insulation Resistance Tester also allows you to store measurements for later review or PC transfer, using the provided software.
• Selectable Voltage Tests: Tailor your tests with user-selectable voltages of 250 V, 500 V, 1000 V, and 2500 V to cover both industrial and solar applications.
• Extended Insulation Resistance Measurement: Reach up to 500 GΩ in insulation resistance measurement for a thorough analysis.
• Intelligent Calculations: Automatically calculate Polarization Index (PI) and Dielectric Absorption Ratio (DAR), minimizing the influence of environmental factors.
• High Measurement Capacity: Execute up to 1,300 measurements at 2,500 V or 6,500 measurements at 250 V on a single charge, enhancing productivity.
• Enhanced Safety Features: Benefit from a CAT IV 600V rating and a built-in voltage alarm function for heightened safety during operations.
The Fluke 1537 has these additional features:
• Extended Measurements: The Fluke 1537 enhances your testing capabilities with AC/DC voltage and resistance measurements.

The Fluke 1760 Three-Phase Power Quality Recorder complies strictly with IEC 61000-4-30 Class-A, for advanced power quality analysis and consistent conformity testing. Designed for the analysis of utility and industrial power distribution systems, in medium and low voltage networks, these power quality monitors give customers the flexibility to customize threshold selection, algorithms and measurements. The Fluke 1760 power recorder records the most thorough detail for user-selected parameters.



Usage



Detailed fault analysis – Performs high-speed transient analysis and finds root causes of equipment malfunctions for later mitigation of malfunctions and predictive maintenance. The fast transient option, with a measuring range of 6,000 V, makes it possible to record very short impulses such as lightning strikes.



Class-A Quality of Service Compliance – Validates the quality of incoming power at the service gateway. Thanks to Class A conformance, the Fluke 1760 allows unquestioned verification.



Correlation of events at multiple locations – Using GPS time synchronization, users can quickly detect where a fault first occurred, both inside and outside the facility.



Galvanic separation and DC coupling – Allows complete measurement of dissimilar power systems. For example, troubleshooting a UPS system by simultaneously recording battery voltage and power output.



Power quality and power load monitoring – Assess baseline power quality to validate compatibility with critical systems prior to installation and verify electrical system capacity before increasing loads.
