What Are The Causes Of Low Voltage In My House?

Low voltage means that appliances and systems will not run as effectively and efficiently. A 90% reduction in the current of electrical systems compared to the normal level is what low voltage is. The main reasons why the voltage lowers is due to electrical faults and issues as well as other external factors. Below are the common situations that result in the voltage of an electrical system being lowered:

Electrical overloading

Electrical overloading is when the electrical system is overworked and there is too much electricity flowing within them. If there are too many appliances drawing out power then the system will not be able to handle this leading to voltage levels being lowered. If there are electrical faults or if appliances have a higher amp level then these can also result in electrical overloading and a decreased voltage level. 

Distance

When electricity has to travel long distances it will mean that the voltage is lower compared to if it was closer. This means that is electricity has to travel a long way then this may be why it is weaker than in other areas of the home. If the main electrical cables to the home take some time to reach the home, such as in rural areas, then this can also influence the voltage levels.

Power disruption imbalances in the wires

Wires that come from the electrical transformer into the home might have power distribution issues which leads to lower voltages. The three wires share the load demand equally but at times the load can become uneven. When this happens, such as from a defect in one wire, the load is overall unbalanced, leading to one wire having more electricity within it therefore over works. This power distribution imbalance in the wires will mean that the voltage is weaker in some areas.

Wire condition

The wires and cables of the home can be the reason why the voltage is so low. When the wires are older this means that they are built to meet the electrical needs of that time rather than today. Alongside how the wires are made, older wiring at times cannot handle today’s electrical needs, causing it to struggle. If the wires are dirty or broken or if the insulation is weak or has been damaged then these issues can also cause there is be voltage levels lowered. 

Accidents

External factors can mean that the power level of the home is lowered or not available. Some of these disruptions include lightning, fallen power lines and electrical distributor errors which can lead to the home’s voltage being lowered. When these issues occur contacting the right source is important to ensure that the diminishing voltage can be resolved.
