Have you ever noticed your lights suddenly dimming and then brightening again? Or perhaps your electronic devices break down faster even though they are still new? This can be interpreted as a signal that there is instability in your home's voltage. Voltage fluctuations are not a trivial issue. If left unchecked, they can damage electronic equipment, increase electricity consumption, and even trigger fires.
The ideal voltage should be around 220 volts. But in reality, voltage can go up and down due to various factors. Here are seven main causes of unstable voltage that you need to know.
Internal Factors from Inside the House
1. Excessive Electrical Load
This is the most common cause. Using too many electronic devices beyond your installed power capacity causes a drastic voltage drop. When the AC, washing machine, and iron are all running at the same time, the power supply gets overwhelmed. A clear sign is when the lights dim as the washing machine starts spinning. As a result, your refrigerator compressor has to work extra hard and wears out quickly.
2. Problems with Internal Electrical Installation
Old or substandard installations are often overlooked. Loose cable connections at outlets or the MCB panel create high resistance. The electrical current becomes intermittent, causing the power to turn on and off by itself. Houses with electrical systems decades old simply cannot handle the demands of modern electricity needs.
3. Humid Environment or Water Leaks
Water is an excellent conductor of electricity. High humidity damages cable insulation, causing current leakage. Voltage becomes unstable because power is lost to the walls or ground. Additionally, moisture triggers corrosion on metal components like cables and terminals, hindering the flow of electricity. This condition is very dangerous and can cause electric shocks.
4. Poor Quality Cables and Components
The temptation of cheap prices often leads to problems. Cables with smaller diameters than standard have high resistance. This results in voltage drop and excessive heat that damages the insulation. Low-quality components like outlets and MCBs break easily and disrupt current stability. Always use components with SNI certification for safety.
External Factors from Outside the House
5. Disturbances in the PLN Network
The electricity network stretches far and wide, making it prone to technical issues. Repair work or trees touching the network cables can make the voltage to your home unstable. During peak load hours in the evening, the voltage naturally drops. Houses at the end of the network also experience weaker current compared to those near the substation.
6. Weather and Lightning Influence
Strong winds can bring cables together, causing sparks. Heavy rain can disrupt the main substation. Lightning strikes produce extremely high voltage surges in a split second, damaging electronics without protection. Fallen trees or animals interfering with the installation can also make the electricity unstable.
7. Short Circuit
A short circuit happens when the phase wire touches the neutral wire directly. This can be caused by frayed cables or a lack of proper protection in the system. If a short circuit occurs at a neighbor's house or on a utility pole, the voltage drops momentarily before the safety device trips. This is felt as a brief flicker of the lights in your home.
Practical Solutions
Have your electrical installation checked regularly by a professional technician. Consider increasing your electrical power if the main cause is an overload. Use a stabilizer or voltage regulator to maintain stable voltage and protect your electronics from fluctuations.
