context_page_description: A brownout is a drop of voltage in an electrical power supply. Brownouts may be done intentionally in order to reduce the load during an emergency. This is done to prevent a total supply failure. Brownouts can also be caused accidentally by faults in the electrical grid which cause a drop in voltage.
context_section_description: A brownout is a drop of voltage in an electrical power supply. Brownouts may be done intentionally in order to reduce the load during an emergency. This is done to prevent a total supply failure ("blackout"). Brownouts can also be caused accidentally by faults in the electrical grid which cause a drop in voltage.
