Info

Over Excitation Limiter• Limits the magnitude and duration ofexcessive field voltage or current• Inverse time characteristic with cool downcharacteristic curve• Dynamic adjustment of pickup based uponhydrogen pressure and cooling airtemperature
Generator Current Limiter• Limits generator line current below adesired threshold• Dynamic adjustment of pickup based uponhydrogen pressure• Bi-directional output allows limiter to raiseor lower excitation depending upon whethersystem is underexcited or overexcited
