The quality and guarantee of our work is ensured by the full implementation of the Greek HOS HD384 standard. With this standard, the requirements of the Electrical Installations are based on the harmonization documents of the HD384 series, which are issued by the European Commission for Electrotechnical Standardization (CENELEC). The specific documents of CENELEC, are models for the creation of a study, the construction, the changes, the additions and the controls of the Electrical Installations in Greece. After all, our goal is to ensure and maintain the reliability and security of the Electrical Installations that we undertake.

The Photovoltaic System is a system consisting of one or more solar panels, with an inverter and other electrical and mechanical systems, which use Sun’s energy to generate electricity. The Photovoltaic System varies in size from small installations on residential roofs or small portable systems, to huge installations of power plants.

Sunlight, which consists of energy beams called photons, falls on the solar panel and generates electricity, through a process called photovoltaic effect. Each panel produces a relatively small amount of energy, but can be combined with other panels to produce larger quantities, as is done with solar panels. The energy produced by a solar panel (or array) is produced in the form of direct current (DC). Although many devices use direct current to operate, including the telephone or laptop, they are designed to operate using the widest power grid, which offers alternating current (AC). So, in order for solar energy to be useful, it must first be converted from continuous to alternating current using an inverter. This alternating current from the inverter can now be used to power appliances locally or be channeled into the power grid for use elsewhere.

Finally, Photovoltaic Systems are divided into two categories:

A UPS system usually consists of:

Depending on their size and destination, power pairs can be accompanied by control panels, automatic switching panels, parallel and synchronization panels.

In order to install a voltage reduction substation, there must be provision and creation of appropriate spaces for the installation of the various machines, such as:

The space in which the machinery of PPC is intended to be installed. (entrance hive, exit hive, protection hive and measuring hive), must be properly designed and constructed, according to the technical instructions and the standards of PPC.

In private areas intended for the installation of machinery (distribution boards, transformers, etc.), it is deemed necessary, in case of emergency, to provide easy access to technicians, as well as the possibility of access to machinery, if deemed necessary.

In general, the lighting of a space varies depending on the type of work we are going to perform in each space. Many times, in addition to the general lighting of a space, it is required (for various reasons) in some places to have more intense lighting. This is achieved by the use of additional lighting fixtures, with the only purpose of highlighting a surface. There are two common types of lighting:

In order to study lighting in an interior of a building, we need to know one of the following elements:

Lighting plays a major role in highlighting volumes and colors, but also in creating a pleasant atmosphere in an environment. With the right lighting in a space we can highlight some points, so that they look even more beautiful and of course give another atmosphere.

Most anti-explosive installation systems have four success factors, which are:

Some anti-explosive systems also have isolation systems using chemicals and mechanisms to avoid high pressure or the passage of flame through pipelines or connected pipes, leading to other areas of our facility with equipment. These isolation systems are activated within five milliseconds when detecting an explosion or fire.

Conditions for a possible explosion, as a result of various reasons, can be created in several workplaces, such as:

Such installations pose a risk of leakage of their materials, resulting in the presence of oxygen in the air, causing ignition and consequently explosion. This applies to gases, vapors, droplets and powders of various materials, which in combination with the widely used in the electricity industry, can cause sparks or the creation of hot surfaces, where when they come in contact with the above forms of various materials, in combined with oxygen, to ignite and consequently explode and / or cause a fire.

The purpose of an ATEX type of electrical installation in such facilities is to reduce the risk of explosive and / or fire conditions, within an acceptable level.

”Grounding” reffers to the path of the electric current, through guided frames to the earth. This avoids the possibility of electric shock from users in the case of a leak, as the current is directed through the metal parts of the building or through the earthing conductor, without the risk of penetrating  any human body.

Each grounding is distinguished by the following characteristics:

In addition, and in combination with the above, we offer lightning protection installation services in buildings, installing lightning rods, which are one of the most important security and lightning protection solutions.

Our company undertakes the study and installation of lightning equipment, always selecting the best and most reliable materials on the market, in order to protect building installations, electronic equipment and people, from the surges that can be caused by a lightning strike.

The solutions we suggest are based on the experience we have gained through many earthing installations that we have undertaken with the elaboration of a relevant study and its application in its entirety.
