Protection Study

The purpose of protection in an Electrical Power System is to act immediately in case of a fault, disconnecting the supply to ensure human safety, equipment protection, and the stability of the power network.

To achieve this, all parameters that may lead to a fault must be clearly identified, and the most effective mitigation method must be determined.

  • We develop the network model using specialized power system software
  • We apply the appropriate protection schemes
  • We perform load flow and short-circuit studies (three-phase, two-phase, single-phase, etc.)
  • We determine the optimal settings for the protection relays to be installed
  • We support the project during the Commissioning phase, ensuring smooth energization of the Substation

These services are applied in Protection Studies for Power Transmission and Distribution Substations, as well as for large consumer installations.

Earthing & Lightning Protection System Study

The earthing system is one of the most critical parts of an electrical installation.
Beyond ensuring proper operation, it provides essential protection for both people and equipment.

A properly designed earthing system is vital for the effective operation of protection devices and for safely discharging high lightning or fault currents to the ground.

Grounding system design and lightning protection study

In any facility — whether it is a Transmission or Distribution Substation, an industrial site, or a residential building — we perform:

  • Measurement of soil resistivity
  • Soil model mapping and characterization
  • Earthing system design and analysis
  • Measurement of grounding resistance, step and touch voltages

Once a proper earthing system is established, we can also perform:

  • Lightning risk assessment study
  • External and internal lightning protection system design

All studies are carried out in accordance with the following international standards and guidelines:
ΕΛΟΤ (ELOT) 60364:2020, IEC 62305-2,3,4, IEEE Std.80-2013, IEEE Std.81-2012, and other relevant standards.

Measurement & Improvement of Electrical Power Quality

Every electrical installation supplied by the power grid is subject to various phenomena that affect its performance and the reliability of its equipment.
The larger and more complex the installation, the more critical it becomes to ensure proper power quality improvement.

Typical phenomena include interruptions (instantaneous, short-term, long-term), transients (oscillatory or impulsive), slow or rapid voltage variations, flicker (voltage dips or surges), frequency deviations, unbalance, and waveform distortion due to harmonics, DC components, notches, and electrical noise.
Some of these originate from the grid, while others are introduced by the quality of the connected loads.

We perform measurements with accredited 2024-generation instruments for Total Harmonic Distortion (THD) and related parameters.

All collected data are analyzed, and a complete report is issued, suitable for use in ISO audits or energy inspections.

To address and mitigate the identified issues, we apply targeted engineering methods, including the use of appropriate harmonic filters—either at the main distribution point or at individual loads—as well as the installation of power factor correction systems (fixed or automatic capacitor banks).

The benefits are multidimensional.

For the facility owner, the most tangible advantage is the reduction of electricity costs, as both the energy demand and kWh consumption decrease.
Equally important, however, is the improvement in installation quality: equipment operates more efficiently, the need for maintenance of electromechanical systems is reduced, and component lifespan increases.
PLC and control electronics maintain synchronization, minimizing production downtime and avoiding operational interruptions in industrial or commercial facilities.

In the past, loads were mostly linear and energy costs were lower; performance was the only real concern.
Today, modern facilities incorporate power electronics (inverters, LED lighting, etc.) that—while improving efficiency and reducing direct operational costs—introduce new harmonic and distortion issues.
These problems become more significant when photovoltaic systems are present, and the overall impact is amplified by the increase in distributed generation and energy demand.
For this reason, power quality assessment and improvement are now essential for every installation.

Our process follows a structured sequence:

  1. A qualified electrical engineer from our team visits your facility to assess the situation at no initial cost.
  2. A proposal is then issued for the first on-site measurement using certified Power Analyzers, to evaluate the electrical performance and enable the preparation of a detailed energy study identifying customized improvement measures.
  3. Following the initial inspection, data analysis and the energy study are completed to define the necessary corrective actions, and a detailed technical and financial proposal is submitted.
  4. Finally, the implementation phase follows, where the proposed solutions are applied to achieve the expected performance results.

Power quality analysis and harmonic mitigation in industrial installations

Medium & Low Voltage Installation Design

To properly serve electrical loads, a Medium and Low Voltage installation must be designed in accordance with European and Greek standards and regulations.

Medium and low voltage electrical installation design

To achieve this, we perform the following steps:

  • Calculate the loads in terms of demand and their behavior with respect to power quality
  • Determine line currents and distribution parameters
  • Design a balanced and intelligent electrical network ensuring smooth and safe operation
  • Dimension and select cable cross-sections
  • Define protective devices and distribution boards
  • Calculate power factor correction and substation sizing
  • Perform earthing study and define the methodology for supplying critical loads

All designs are developed with the aim of achieving optimal equipment operation across all load profiles, ensuring high energy efficiency, environmental responsibility, and long-term sustainability.

In large-scale facilities with multiple networks, it is also essential to perform a cable routing study to determine the most suitable underground and aboveground paths.
This prevents future modifications and ensures safe coexistence with other utility systems such as gas or heating networks.

EV Charging Infrastructure Design

According to global forecasts, by 2035 every new car sold will be fully electric, reducing worldwide CO2 emissions by approximately 30%.

To achieve this transition, two key conditions must be met: first, electric vehicle technology must reach a level that fully serves user needs, and second, a sufficient and reliable EV charging network must be in place.

EV charging infrastructure design and study

Our company provides complete EV charging installation studies for both public and private networks, including:

  • Power flow calculations during charger operation
  • Determination of appropriate protection settings
  • Implementation of dynamic load management to maximize simultaneous charging capacity
  • Dimensioning of new or expanded electrical service connections
  • Ensuring uninterrupted operation of the facility’s main electrical loads during vehicle charging

The rapid adoption of electromobility not only reduces the environmental impact of transportation but also introduces new challenges to electrical infrastructures.
If not properly addressed from the design stage, these challenges may lead to network instability or insufficient charging performance.
For this reason, our company provides comprehensive engineering studies and solutions for reliable and efficient EV charging systems.
