What Happens During A Brownout

What Happens During A Brownout

Are the lights in your house going dim? Do you have appliances making funny noises at certain times of the day? Are you wondering what happens during a power brownout and what it is? We can help with that.

During a power brownout your will notice your lights going dim. This is due to the power utility not being able to keep up with the demand of the power grid. It causes a drop in voltage during high power usage times on their electrical system. This results in lights going brown or dim.

This results in lights going brown or dim. Many people complain about these electrical brownouts. When there is a brownout, there is a chance for flickering of the lights.

The flickering happens because of the power grid not being able to keep up with the power needs of consumers. If the power grid system does not have enough power for all the power users then there will be a short in the power grid.

What Happens During A Brownout And Things You Can Do To Avoid It

Have a plan in place before it happens.

Determine what you should do in the event you lose electricity for a long period of time. Are you going to be out of power for hours or for days? Plan how you will deal with it. Prepare an emergency power pack for you and your loved ones. Let you neighbors know that you will be without electricity for a period of time. Don’t expect them to come help you. Instead, do it yourself.

Let them know that you need their help only if it is an emergency. Here is a list of things you can do when your power goes out. Light a candle if you can, but be careful not to burn your house down.

Turn your phone on and check the text messages for messages to help pass time.

What Happens During A Brownout And Things You Can Do During A Brownout

Some things you can do to help you stay cool during a power outage is to:

Stay in the house as much as possible. Keep the air conditioner turned down if you have one. This will reduce the cooling load on the system. If you have a pool, keep it filled.

Don’t operate any major equipment that uses electricity.

This includes: HVACs, dishwashers, washing machines, dryers, electric water heaters, microwaves, stoves, etc.

If you do need to use any major equipment, turn it off first. Keep fans, ceiling fans, and dehumidifiers running in your house as much as possible.

Remember: Cooling your house with fans will not reduce the amount of power usage on the electric grid. During a Power Outage, Turn Off The Thermostat.

You Don’t Want To Use The Air Conditioner If You Are Not Using It.

What Is A Power Brownout

Brownouts are due to power utilities coming to a screeching halt due to equipment failures.

There may also be equipment failures in other areas that the power utility must take care of. This is why you may experience brownouts in neighboring areas that are already experiencing brownouts.

The power utility cannot carry all the load and the load is being distributed.

How Can I Stop A Power Brownout

A power brownout is not just limited to residential homes.

Large commercial buildings, businesses, and hospitals will also experience a power brownout. During a power brownout there are a few things you can do to keep from having an outage or power failure on your home or business. Generator Safety If you have a generator for use in an emergency situation, it is important to keep your generator at the highest level of maintenance.

You need to keep your generator filled with fuel to keep the fuel from catching on fire. You should also keep your generator turned off until the power is restored.

If you decide to plug in your generator, make sure you do so inside a well ventilated area.

What Is Voltage Drop

Voltage Drop is a term used in the electrical industry to describe the rate of voltage in the transformer from grid to load.

Voltage drop means there is less voltage at the top of the transformer where it passes to the load then as it nears the bottom of the transformer it is increased causing a higher voltage.

In a severe power outage, the transformer may overload and turn off. The overload may be caused by a power failure in the grid or line or system equipment.

If the voltage drop is large enough it could damage equipment, break loose supports on the structure, or create a circuit that can arc and cause damage. Is the black out one way?

In a few hours the power utility will start to restore power to those affected by the power black out. This is the first step in restoring power.

Will Voltage Drop Hurt My Electronics

According to Energy Star, Volatile Energy: Energy Use, Opportunities, and Implications,

“Voltage drop is a non-destructive effect on equipment. The energy lost when voltage is reduced to low levels is lower than the energy necessary to replace any loss in equipment.” If this sounds dangerous, you’re right. However, while your devices might start to burn out, you’ll be safe.

Electronics use a lot of power and this voltage drop will cause your computers and printers to shut down. The servers in your computer will stop running and your internet connections will go out. Things like the air conditioning in your home could be affected as well.

That said, most computers and electronics will survive a brownout.

Is It The Same As A Power Outage

Brownouts, not to be confused with power outages, are more common than outages, which are rarer.

They are often caused by a large power failure such as the wind or storms affecting the power grid. When this happens the power will be cut off for as long as it takes for the power grid to come back online. When this happens the power will go off, and as you have noticed your lights are dimming.

This is the power utility slowing the pace at which they are using power, in order to keep the energy usage stable. When this happens, the lights will slowly go out.

When is a Power Brownout Not A Brownout? You may be asking, what is a power outage? A power outage means that there is a power outage in your area and the lights are not dimming.

This can happen in very specific circumstances.

Should I Get A Generator

During a power brownout you should immediately get a generator in your home to help sustain power if the power goes out. This will ensure that you have power when the power goes out.

The use of generators during a power brownout is not recommended because the power may be lost sooner than expected. Once the power goes out, a generator is not capable of restoring power. So getting a generator now is important to be ready for that situation.

What Equipment Should I Have In My Generator? In a generator, you will find a large gas tank or diesel fuel tank, a power inverter, a 120V to 240V, high pressure fuel pump, a fuse panel, and several heaters, etc.

How Much Power Can I Generate? On average, your generator can generate around 3,000-5,000 watts.


Other lights will be dimmed at that time, but this will not necessarily mean that your power is being cut off. This simply means that you are experiencing the risk of a power brownout.
