Generators provide the power for the entire electrical grid. Multilin relays protect generators during
external disturbances. |
Multilin products allow utilities to implement system stabilizing and cost saving options previously
considered impossible. |
Asset protection is critical - revenue generating processes demand reliable protection that is flexible,
easy-to-use, and able to withstand harsh environments. |
