Brownouts
A brownout occurs when the power supplier reduces
electrical voltage. This is done to force our appliances
and lights to use less electrical power (watts). The
lights will dim slightly. Generally, voltage reductions
are advertised on radio and television. When they occur
take the following steps:
1. Turn off all lights and appliances except those which
are absolutely necessary.
2. Delay jobs like dishwashing and laundry until after the
brownout is over.
3. Turn off all air conditioning if it is operating,
unless it is necessary for a person's health.
4. If you have an electric range, plan meals which require
a minimum of cooking.
If everyone will cooperate and reduce electrical
consumption, the duration of the brownout will be reduced.
It is also important to continue to conserve energy
immediately following the brownout or voltage reductions
may again have to be put into effect.
The power suppliers do reduce voltage more than 10
volts below normal during a brownout, which for limited
periods of a few hours will not cause damage to a
consumer's equipment. If a reduction in power is not
planned by the power company, shut down all equipment with
motors. The low power could cause the equipment to burn
out the motor trying wiring supplying the equipment. An
electrician should be called to check out the problem.
