In a world increasingly dependent on electricity, the protection of electrical installations is an essential factor in guaranteeing the safety of people, equipment, and infrastructures.

Whether in residential, commercial, or industrial environments, all electrical systems are subject to phenomena such as voltage spikes, which can have serious and unexpected consequences.

Fortunately, ASLO has an effective solution to mitigate this type of threat!

 

What is a power surge?

A surge is a sudden and abnormal increase in electrical voltage, and can happen for several reasons:

• Atmospheric discharges (e.g. lightning, in adverse weather conditions);
• Voltage spikes;
• Shifts on the electricity grid (e.g. sudden connections/disconnections by energy distributors);
• Equipment problems (e.g. motor or generator failures).

These surges can have serious consequences, from burning out electronic devices to resulting in electrical system failures.

 

What is a surge protection device?

A surge protection device (or SPD) is a device that protects the electrical installation against the points mentioned above.

By diverting excess energy to earth, these devices prevent it from reaching equipment connected to the mains.

 

What types are there?

Surge protection devices are generally divided into three types:

Type 1 – They protect against direct lightning strikes. They are used in buildings with lightning rods or with an elevated risk of direct impact.

Type 2 – These are the most common, installed in distribution boards to protect against induced surges or those caused by shifts on the electrical grid.

Type 3 – They protect specific equipment (e.g. computers, televisions) and are installed near sockets as an additional reinforcement.

 

What are the main benefits?

• Protection of electronic equipment – extends the service life of computers, televisions, household appliances, etc.
• Reduced costs of breakdowns – no need for repairs or replacement appliances.
• Safety – minimises the risk of fire or electrical accidents caused by surges.

 

Where should they be installed?

SPDs are usually installed in the main distribution board of the home or building, where they provide general protection.

In locations with sensitive or high-value equipment, it is common to combine different types of protection: for example, type 2 SPD in the main distribution board and type 3 at specific points.

Installation must be carried out by a professional to ensure the effectiveness of the device and guarantee its safety.

 

ASLO’s surge protection devices therefore act as a first line of defence, protecting not only your equipment but also the electrical installation itself.
