YOGYAKARTA - Electric meters that suddenly drop will certainly be a troublesome problem. Moreover, at this time electricity is one of the main needs in everyday life, whether it's at home, school, or office. In addition to disrupting daily activities, electricity meterlets often also have an impact on damage to electronic equipment. So, what causes electricity to often drop or drop?

Electric Engineering Lecturer, Faculty of Engineering, University of Indonesia (UI) Budi Sudiarto revealed, there are several factors that cause the electric meter to fall. First, electricity will drop when the load flows beyond the rating capacity of the Miniature Circuit Breaker (MCB) cut. As an illustration, the MCB in the house functions to limit electricity.

For example, MCB at home uses 900 VA or 4A. When the current flows above that number, electricity will drop," said Budi.

He revealed that the drop meter was the result of a power cut by MCB which consisted of two principles, namely the principle of heat and electromagnetic principles.

The principle of heat will be exploited when MCB decides on the flow due to excessive load in the electricity, with a capacity that is not too large.

Meanwhile, the electromagnetic principle was used when MCB detected a short circuit in electric currents.

"If a short connection occurs, the electricity will be cut due to damaged equipment or occurs due to damaged cable installations," said Budi.

The next factor is that the MCB used has been damaged, weak, and is very sensitive to electricity. Damaged MCB may occur due to the use of electrical devices in the house often changing voltages.

As a precautionary measure of electricity that often falls, Budi provides advice on using electricity according to the capacity used at kWh meter. In order not to fall, the public can arrange several high-voltage electrical devices to be used alternately. However, if you have already dropped, it is advisable to disable all electrical equipment first.

If it has gone down or dropped, try to turn it on first. We'll see (electronic devices) one by one first," he said.

If the meter drops again when turning on the electronic device, it is most likely caused by overload.

However, if the electricity load has been regulated and minimized and the meter continues to fall, the public is advised to check the MCB.

Electricity in the house that easily plummets without overload is likely to experience a short circuit or MCB damage.

That's a review of why electricity often drops and how to deal with it. Visit VOI.id to get other interesting information.
