Fluke Insulation Tester, 5 MΩ to 1 TΩ Insulation Testing Resistance, 250V to 5000V Test Voltage - FLUKE-1550C FC w/IR3000


This insulation tester is a portable instrument for assessing insulation resistance on high-voltage electrical assets and supporting preventive maintenance programmes. It operates from an internal lead‑acid battery and pairs with a wireless connector and mobile app to capture, trend and store measurement data remotely, improving on-site decision making and worker safety during tests.

Features & Benefits


• Selectable test voltages from 250V to 5000V enabling tailored diagnostics
• Measures insulation resistance up to 1TΩ for high-resistance detection
• Rechargeable Yuasa NP2.8-12 battery powered tester offering 750 tests
• CAT IV 1000V safety rating for use on industrial distribution systems
• Guard system reduces surface leakage influence for cleaner readings
• Timer function to 99 minutes for controlled timed measurements

**Applications**


• Suitable for insulation assessment of switchgear and transformers
• Ideal for motor and generator insulation condition monitoring
• Used for cable acceptance testing and site commissioning
• Can be used with asset trending systems for predictive maintenance

What range of resistance can I expect to measure accurately?


The instrument provides resistance measurement capability up to 1TΩ and includes a bar-graph visualisation for large-range readings.

How is live-voltage presence handled before a test?


It warns of line voltage presence and displays voltages up to 600V AC/DC so users can confirm circuits are safe to test.

What environmental conditions does it tolerate during operation?


It functions between -20°C and 50°C with humidity ratings that decline from 80% at 31°C to 50% at 50°C and is specified for use up to 2000m altitude.

What measurements beyond resistance does it perform?


It measures leakage current from 1nA to 2mA, capacitance up to 20.00μF, and offers a ramp test for breakdown evaluation.
