APPLICATION AND SYSTEM INTEGRATION
In utility-scale power generation and heavy manufacturing plants, insulation breakdown in high-voltage motors and transmission cables leads to costly unplanned downtime. The Fluke 1550C addresses this by automating Polarization Index (PI) and Dielectric Absorption Ratio (DAR) calculations. Its high Technical Compatibility with modern asset management systems is supported by infrared and wireless data transfer, allowing maintenance teams to log historical trends and identify insulation degradation before failure occurs.
