Extreme cases of voltage fluctuation can cause heavy damage to your life and property. As a safety measure, it is important to investigate the root cause of the voltage fluctuation in your household or office. There could be a number of reasons for the unstable flow of electricity across a building.
- Can voltage fluctuations cause fire?
- Is it normal for voltage to fluctuate?
- What happens when voltage fluctuates?
- How much voltage fluctuation is acceptable?
Can voltage fluctuations cause fire?
If left unchecked, voltage fluctuations can cause extensive electrical damage and lead to fires. It could damage appliances and fixtures on that circuit, which could result in making costly replacements.
Is it normal for voltage to fluctuate?
When the battery's state of charge is low, the voltage is raised slightly to quickly put the charge back in. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gauge, you may see the voltage move up or down. This is normal.
What happens when voltage fluctuates?
Voltage fluctuations degrade the performance of the equipment and cause instability of the internal voltages and currents of electronic equipment. However, voltage fluctuations less than 10% do not affect electronic equipment.
How much voltage fluctuation is acceptable?
The National Electrical Code allows up to a 5% drop. There can be a <3% drop in a feeder and an additional <3% drop in individual branch circuits. Utilities actively regulate distribution voltages slowly by means of tap changing regulators and by switching capacitors to follow changes in load.
