Should You Solve Electrical Problems at Home Yourself?

A lot of electrical works problems at home are actually minor cases that you can solve yourself by turning off the main circuit breakers and either applying electrical tape, replacing the wire, or adding or replacing other fixtures that could pose a hazard, such as faulty power outlets and light sockets.

Home Repair and Safety

When fixing these things yourself, safety is the most important factor to consider. Before working with the problematic power/light socket/exposed wire, be sure to turn off the main power switches, which is usually located at the circuit breaker.

Make sure to secure each exposed wire with proper insulation (i.e., electrical tape). For light sockets and power outlets, make sure that these are all in good condition before screwing in place and turning the main power switches back on.

However, there are certain instances when you should contact an electrician or an electrical services company to help you out. This article will help you get started on the different things you need to know when it comes to hiring an electrical service company.

What is An Electrician? (And Why Do You Need One?)

An electrician is the person maintains and installs electrical and power systems for both residential and industrial areas, as well as different types of electrical equipment and machines. They may specialize in either construction or maintenance, though they usually are able to handle both.

For electricians specializing in construction, they are in charge of installing wiring systems into factories, buildings, and homes. Electricians that specialize in maintenance, meanwhile, repair and/or upgrade existing electrical systems and equipment.

Their work with the blueprints, which are technical diagrams that show where the circuits, outlets, load centers, and other equipment are located. Once they know where the different wires and components go, they will be able to make the necessary installations and/or repairs, if necessary.

Whether it’s industrial or for domestic applications at any place in Singapore, a good electrician like power max in Singapore who is well-equipped with both the necessary knowledge, experience, and tools will be more than able to help you get the job done.

Electrical Faults

An “electrical fault” is what is described when voltages and charges deviate from their supposed values on the meter. Under normal conditions, power systems equipment carry nominal currents that allow the entire system to operate safely.

When a fault occurs, excessively high currents can flow into and overload all kinds of equipment and devices, which can damage them permanently. Having an early detection device is necessary in order to prevent this from happening.

There are two main categories of electrical faults:

1. Symmetrical

Also called “balanced faults”, these types of faults have quite severe effects on power systems. The two types of balanced faults are, namely, line-to-line-to-ground (or LLLG), and line-to-line-to-line (LLL).

This type of electrical fault rarely occurs, making up as much as 2 to 5 percent of all system faults. Analysing these faults is usually easy and is carried out on a per-phase basis. When it comes to selecting set-phase relays and rupturing capacity and switchgear evaluation, a three-phase fault analysis is usually required.

2. Unsymmetrical

Unsymmetrical faults are more likely to happen to your power system, though they have a lesser impact. The three types of unsymmetrical faults are line-to-ground (LG), which is the most common, line-to-line (LL), and double line-to-ground (LLG).

LG faults occur then active line makes contact with the ground. LL faults occur when an active, exposed line touches another, and LLG faults happen when two active, exposed lines make contact with the ground.

These faults are also often called “imbalanced” faults, as they can cause an imbalance to the system. While analyzing unsymmetrical faults are also carried out on a per-phase basis, they are more difficult to analyze compared to symmetrical faults.

These faults can either be caused by equipment failures, such as a malfunctioning circuit breaker or a switching device, or by other factors, such as bad weather conditions (typhoons, tropical storms, etc.), smoke and fire, or by human error.

When left unmitigated, these faults can result in not just current overflow, but also to loss of equipment and a potential electrical and/or fire hazard to nearby operating personnel. The job of an electrician services company, then, is to make the necessary repairs in these instances and install measures and devices to prevent accidents from happening.

Types of Services Offered

Electrician services are often different for both industrial and domestic areas, and these services may vary depending on the quality service that a good electrician service in Singapore would be able to provide. Here are some of the many services that electrical works companies offer for both industrial and domestic:

• Power failure analysis – A licensed electrician employed by the company will be sent over to your building in order to inspect your power systems and find the cause of your power failure.

• Short circuit repairs – A short circuit can occur when an active wire and an inactive wire touch each other. A lot of current then flows from the active wire to the inactive one, resulting in either a blown fuse or a tripped circuit breaker.

• Circuit breaker replacement – A tripped circuit breaker can either be the result of a short circuit or a ground fault, which in turn could result in a temporary power outage for that particular line as a safety measure to avoid overloading.

• Upgraded wiring/Rewiring – Wires can deteriorate under harsh conditions or be stripped of their insulation, which can cause a potential electrical or fire hazard.
