COMPONENT OF THE WEEK
The Fluke 1587 FC is a 2-in-1 Insulation Multimeter (also called an Insulation Tester Multimeter). It combines a digital insulation resistance tester with a full-featured True-RMS digital multimeter in one compact handheld tool.
It is designed for troubleshooting, preventative maintenance, and commissioning of electrical systems, allowing users to perform both routine multimeter measurements and high-voltage insulation testing safely. The "FC" version includes Fluke Connect wireless connectivity for remote monitoring, data logging, sharing results via smartphone, and advanced diagnostics like PI/DAR (Polarization Index/Dielectric Absorption Ratio) tests.
INDUSTRY APPLICATIONS
The Fluke 1587 FC is widely used in industrial and electrical maintenance environments where insulation integrity and electrical troubleshooting are critical.
The Fluke 1587 FC is widely used in industrial and electrical maintenance environments where insulation integrity and electrical troubleshooting are critical.
✅ Motor and drive maintenance : Testing motor windings, cables, and variable frequency drives (VFDs) for insulation breakdown, contamination, or moisture. It is especially useful for hybrid vehicles and industrial motors.
✅ Industrial electrical systems : Preventative maintenance on switchgear, transformers, generators, and distribution systems.
HVAC/R — Checking insulation on compressors, motors, and control circuits.
✅ Renewable energy (Solar/Wind) : Commissioning and troubleshooting inverters, cables, and panels (Fluke highlights it for solar professionals).
✅ Facilities maintenance & building electrical : Insulation testing on wiring, panels, and equipment to prevent failures.
Manufacturing and process industries : Routine testing of pumps, conveyors, and other electrically driven machinery.
Utilities and field service : Troubleshooting and commissioning in power generation/distribution.
