Frequently Asked Questions
What makes the Fluke 1555 suitable for testing the widest range of high-voltage electrical equipment?
With selectable test voltages from 250 V up to 10 kV and insulation resistance measurement to 2 TΩ, the 1555 can test everything from low-voltage controls to utility-scale power systems in a single instrument.
What types of electrical infrastructure benefit from testing with a 10 kV insulation resistance tester?
Utility power distribution cables, high-voltage transformers, substation switchgear, industrial transmission equipment, and telecommunications infrastructure all require periodic 10 kV insulation testing to maintain reliability and safety.
How do automatic DAR and PI calculation features improve the quality of insulation assessment?
DAR (Dielectric Absorption Ratio) and PI (Polarization Index) calculations help identify hidden insulation degradation that simple resistance measurements might miss, enabling early detection of potential equipment failure.
Can the 1555 be used to monitor trends in insulation condition over time?
Yes, the 1555 stores test results in 99 labeled memory locations, enabling you to track insulation resistance trends across multiple testing sessions and identify gradual degradation patterns before failure occurs.
