Definition of Voltage Sags

Voltage sags are conditions where the electrical voltage experiences significant fluctuations, either increasing or decreasing suddenly from the normal stable voltage level.

Typically, a home experiences voltage sags when the supplied electrical voltage falls below the standard level necessary for the normal operation of electrical appliances.

In Indonesia, the standard electrical voltage for residential and commercial use is about 220 volts. When the voltage drops significantly below this figure, it is referred to as low voltage or voltage sags.

Voltage sags require special attention as they can disrupt productivity and safety in both household and industrial environments.

If not promptly addressed, voltage sags in homes or buildings can lead to various problems. Thus, understanding and addressing voltage sags is crucial to maintaining the reliability and efficiency of electrical systems.

Dangers of Voltage Sags

Voltage sag conditions can lead to significant dangers and issues, including affecting electronic devices and other electrical equipment.

Electronic devices and electrical appliances operating below the recommended voltage can experience damage or faster wear and tear.

Additionally, voltage sags make electrical equipment operate less efficiently, resulting in higher energy usage to achieve the same output, which can ultimately increase electricity bills.

Furthermore, wires and electrical components operating under low voltage can overheat, raising the risk of fires.

Voltage sags can also impair the functionality of safety devices, such as fire alarms or security systems, thereby endangering user safety.

Causes of Voltage Sags

1. Poor Quality Cables and Equipment

The first cause of voltage sags can stem from low-quality or improperly specified cables and equipment. This not only risks causing voltage sags but also other electrical disturbances. Cables with inadequate diameter or unsuitable materials can increase resistance and reduce voltage.

2. Loose Connections

Loose or poor connections between cables or other electrical components can cause voltage drops, leading to voltage sags. Poor connections increase resistance at the connection points, resulting in power loss and voltage reduction.

3. Environmental Factors

Environmental conditions such as high temperatures, humidity, extreme weather, and lightning can affect the performance of the electrical distribution system and cause voltage sags. For example, excessive heat can increase cable resistance, while high humidity can cause corrosion on connections and electrical components.

4. PLN Network Disturbances

Disturbances in the PLN (State Electricity Company) network are also a common cause of voltage sags. Frequent issues include cable and network support errors, problematic transformers, rolling blackouts, and suboptimal protection and relay systems.

Ways to Overcome Voltage Sags

1. Using a Stabilizer Device

One of the most effective ways to overcome the dangers of voltage sags is to use a stabilizer device, which functions to stabilize the electrical voltage entering your home. With this device, your electrical appliances receive a constant voltage supply.

Stabilizers can protect electronic devices from damage due to unstable voltage and reduce the risk of electrical short circuits.

2. Installing Quality Electrical Equipment

Choosing quality electrical equipment is crucial for maintaining stable electrical voltage. High-quality devices usually have additional protection and are more resistant to voltage fluctuations.

Select devices from trusted and tested brands and always pay attention to the safety certifications of the equipment.

3. Contacting PLN Immediately

If voltage sags occur in your home without any issues in the installation upon inspection, the main disturbance might be in the PLN network. To address this, promptly report the voltage sags in your home to PLN for inspection and repair.

Note the time and frequency of the voltage sags and report the issue to PLN customer service by phone or app. Request PLN personnel to come and inspect the electrical installation in your home.

4. Using Electrical Energy According to Regulations

Using electrical energy according to the set rules and limits is also crucial to prevent voltage sag issues. Avoid using electrical devices that exceed the available power capacity in your home.

Do not use too many electrical devices simultaneously and always remember to turn off unused electrical appliances.
