Keeping Wind Turbines Turning

Look to Littelfuse for circuit protection and sensing solutions that boost the performance of wind turbines and the efficiency of wind energy transmission. Our industrial power fuses and surge protective devices prevent damage to generating equipment, power lines, and transformers. We also make arc flash relays, thermistors, dc disconnect switches, and temperature sensors for turbine components.

Protecting Wind Turbines from Arc Flash

An arc flash is an intense discharge of electrical energy across a typically insulating barrier, resulting in extreme heat, pressure, and light that can destroy equipment and cause temporary blindness. Causes of an arc flash in a nacelle include insulation breakdown, loose connections, or mechanical damage that generates phase-to-phase or phase-to-ground faults.
