No Power


no powerDo you have no power at home?

So as to be better prepared to deal with the consequences of no power, it is important to get an understanding of the causes of power failures. This would help to ensure that you have all the necessary safeguards in place to ensure that you can deal with power outages in the best possible manner.

Main causes of power failures:

  • Natural causes: this is the single most common factor responsible for the majority of power outages. Weather conditions such as heavy rain, lightning, snow, wind, ice, etc. can lead to power failures. While it may be difficult to safeguard against natural calamities, steps can be taken to protect electrical systems from more common occurrences such as water and dust. Water can severely affect electrical components such as wires, switchboards and circuits. This can lead to expensive electrical repairs and replacements. Dust can also have major consequences on electrical systems leading to short circuits and power outages.                                                                                                                                                     Natural calamities such as tornadoes, hurricanes, earthquakes, floods, etc. can all cause serious damage to electrical equipment. Additionally they offer very little time to safeguard against, increasing the scale of damage caused.
  • Short circuits: are another common cause of power failure. The reason for short circuits occurring is current travelling along the wrong path in an electrical circuit. Short circuits could be caused due to the insulation of the wires wearing out or some external conductor such as water which has been mistakenly added to the circuit.

Other causes of power failures

  • Vehicle accidents and animals: vehicles crashing into electric poles cause power lines to break leading to power outages. Animals which come into contact with electrical equipment such as transformers lead to its failure and result in power outages.
  • Electrical equipment failure: the different electrical components which make up the system could fail as a result of general wear and tear over the years or due to other factors. Natural causes such as those mentioned above such as lightning strikes could cause electrical equipment to get damaged and result in failure.
  • User’s electrical equipment: power failures could also be caused as a result of overuse of electricity inside the house which trips the circuit breaker and results in a power failure. The solution to this issue is to turn off some of the electrical appliances in the house or the alternative is to improve the wiring inside the house. Also, power outages could result due to defects in a particular electrical appliance being used in the house. This faulty appliance could trip the circuit breaker and result in a power outage. Disconnecting the faulty appliance and resetting the circuit breaker would be the solution in such a case.

Types of power outages

  • Brownouts: this refers to a drop in the power supply which results in a voltage drop leading to dimming lights. Electrical equipment such as motors and generators are particularly at risk in the instance of brownouts as they could overheat. If you face regular brownouts, it is advisable to install a backup power system. This will provide the required power during the times of voltage drops.
  • Blackouts: are a total loss of power to a particular area and are the worst kind of power outage. Restoring power in such cases is often the task of the power station. However, this could take significant amounts of time depending on the particular electrical network affected.
  • Power surges: these could lead to the overheating and damage of important electrical equipment. Surge protectors and circuit breakers offer some degree of protection against power surges.

How to respond when there is no power?

The first thing that you should do in case of a power outage is to check your immediate neighbour’s power. This is to determine if your neighbour’s power has gone out as well or if it’s just your house. If it’s just your house, then you should check to see that the circuit breakers and the ground fault circuit interrupter are in the down position. If they are in this position, then try pushing the breakers upwards after disconnecting all equipment that you were using and see if the power comes back. If it doesn’t, call the electrician Sydney trusts when it has no power on (02) 8583 2337. We will send one of our team members to come out and get your power going again!

If your neighbours as well as you have no power, then you would have to call the electricity company. They would be able to provide you with updates regarding the status of the power. Also, remember to turn off all your appliances in such a situation and ensure that any materials which could become possible fire hazards are at a safe distance. Leave just one light on so that you know when the power comes back.
