The classic problem of homeowners is an inevitable brownout, which frequently happens, especially when it rains, thunder, lightning, or even when a storm hits. Of course, the more frequent brownouts, the more damage to appliances. So HomeGuru is here to guide you and solve the power outage in a simple, one-stop way, no more worrying about power surges in the rain and thunder.


Assorted power outages and power surges every time it rains and lightning, HomeGuru will bring you a simple solution with a helper that will make the power outages go away, safe for your home devices.

What are the causes of brownout and power surge?

Problems with electrical circuits in the house, whether a power brownout, overvoltage, electrical surges, also affect various devices in the home. First of all, let’s understand what these 3 problems are caused by.

1. Brownout

The power brownout problem is caused by the voltage that comes to us is lower than 220V, resulting in not being able to supply enough electricity. The noticeable symptom is that the power will turn on and off. There are also other reasons as follows.

• There has been a struggle for electricity, especially in villages or communities where many houses have to compete for electricity, causing frequent brownouts.
• It is far from the power station, causing the voltage to drop as the distance travels.
• Heavy rain or storms result in power outages and power outages.
• Use electrical appliances that have high rotation motors
• Faulty electrical wiring in your home.
• Electricity goes to the ground.
• There is a problem with electrical conductors in your home or building, such as a power failure or electric shock.

2. Overvoltage

In the case of overvoltage, that is, in the circuit, the voltage transmitted is greater than 220V. It will only occur for a short time, not causing severe consequences or affecting electrical equipment as problems with power cuts or surges.

3. Electrical surge

Caused by the voltage that is delivered in a short time, which the surge problem will adversely affect the type of electrical appliances that use resistance or coils, such as irons, light bulbs, kettles, rice cookers. There are many factors such as

• Faulty wiring or incompetent wiring.
• The power system fluctuates.
• Inclement weather such as rain, thunder, storm.
• Turn on several electrical appliances at the same time, such as air conditioners, refrigerators.


How to notice the electric brownout.

• The lamp is on, but the brightness is less noticeable
• The lamp is rarely on, has flickering symptoms, sometimes it’s difficult to turn on, having to turn it on – repeat several times.
• The water pump does not work, or the device with high motor speed does not work.
• The problem of the air conditioner is not cold, slow or not working.

Realize that brownout causes more problems than you think.

If you encounter frequent brownouts, what will happen later is that your home appliance has a problem. Due to inconsistent voltage, resulting in different electrical appliances cannot work fully, the internal electrical circuit is damaged. This can ultimately shorten the lifespan of various devices. Sometimes it can even be fatal, especially air conditioners, TVs, refrigerators, and computers that need constant electricity to run.

In addition, when electrical appliances in the house have problems that cannot function at their full potential, they can cause heat build-up inside the device. If brownout or power surges are frequent, problems with the internal electrical circuits will become more serious, leading to future fire causes.


How to deal with brownout problems with a good helper.

If your home faces power surges, frequent brownouts, or intermittent power outages, it’s advisable to fix the problem asap to prevent more severe problems.

1. Turn off electrical appliances.

In the event of a power failure, the first thing to do is turn off the electrical appliances or devices that are using a lot of electricity. After that, observe if the voltage inside the house is back to normal or not. For example, if we turn off the air conditioner or air conditioner, light bulbs that are dimly lit at that time come back to normal light or not. If they come back to be brighter than before, it means that the cause of the power drop is caused by that type of electrical appliance that has just been turned off.

2. Use an electric control device or an automatic voltage stabilizer.

Suppose you don’t want your home to suffer from power outages, power surges, or intermittent power outages. In that case, we recommend installing an electrical control device, also known as an Automatic Voltage Stabilizer, that will adjust the voltage to be consistent at 220V. As a result, various types of electrical appliances can be used continuously. The key is not to damage your home appliances from frequent brownouts.

In addition, the advantages of using a stabilizer are:

• It automatically cuts and reconnects the power to keep the voltage stable.
• It can work continuously without having to constantly monitor or turn on and off the machine.
• Good resistance to surges
• Houses equipped with stabilizers will notice no power failures, unlike houses that don’t have stabilizers.


3. Use Uninterruptible Power Supply (UPS)

Another device that helps solve power brownout and power surges are Uninterruptible power supplies, or UPSs, commonly used in homes with many electronic devices. Especially those with complex operating systems such as computers, CCTV cameras, water pumps, or even smart TVs that can be damaged if the power system has a problem or failure, such as data loss.

The advantage of choosing a UPS is that it will tell you the duration of the backup power to prepare in different situations. The important thing is that the device has protection for overload and short circuits.

4. Install a step-up transformer

Another solution to frequent brownouts is to install a Step-Up Transformer which must be manually adjusted. For example, when the brownout has to be adjusted to increase the voltage to 220V. But if the power is overloaded, the voltage must be reduced to 220V, which is suitable for outdoor use or no equipment. So much electricity. It is an ideal device for those who are ready to adjust the pressure at all times.

5. Use an extension plug with Surge Protection system

In addition to installing an uninterruptible power supply or a stabilizer, choose a power outlet or extension cord with built-in Surge Protection. It will only work for a short time. The plug will only work at its full potential when used in a properly grounded home.

It’s all over how to deal with brownout problems that can easily occur in different situations. If you find yourself dealing with frequent brownouts, you need to be prepared in advance to don’t. Damages various devices and electrical appliances in the home. But suppose you want to get products to help solve the power outage.
