Fluke 1555 FC 10 kV Insulation Tester

The Fluke 1555 FC 10 kV Insulation Tester sets the standard for high-voltage insulation resistance testing, combining advanced measurement capabilities with wireless connectivity and remote operation. With the Fluke Connect® mobile app, you can operate the tester, monitor real-time results, and analyze data directly from your smartphone, keeping you safely away from potentially hazardous energized equipment.

Designed for switchgear, motors, generators, transformers, and high-voltage cables, the 1555 FC supports insulation testing up to 10 kV with a measurement range up to 2 TΩ, making it ideal for commissioning, troubleshooting, and preventive maintenance. It automatically calculates Polarization Index (PI) and Dielectric Absorption Ratio (DAR) for deeper insulation quality analysis, while the ramp function provides controlled breakdown testing.

The tester’s guard system eliminates surface leakage effects for highly accurate high-resistance measurements, and selectable test voltages—in 50 V increments from 250 V to 1 kV and 100 V steps above 1 kV—offer unmatched flexibility. Its large digital/analog LCD ensures excellent visibility, while 99 internal memory slots allow you to store, label, and recall results easily.

With the Fluke Connect desktop software, creating professional reports is simple and efficient. The CAT IV 600 V / CAT III 1000 V safety rating, line-voltage detection, IP40 protection, and 3-year warranty make the Fluke 1555 FC a robust and reliable solution for critical insulation testing applications.
