The first and most typical symptom of an electrical leak is the sudden tripping of circuit breakers or residual current relays, even when no device is operating. This means that the current leaving the phase in the system does not return equally through the neutral. This difference may be directed to the soil through the … Read more
In order to plan, dimension, calculate and evaluate grounding projects in electrical installations, there is a need for theoretical and practical basic knowledge, as well as standards, regulations and computer-aided programs that are valid in every project. The healthy installation and operation of electrical facilities is very important for the safety of life and property. … Read more
It wouldn’t be wrong to say that e-mobility is the integration and optimization of transportation infrastructure suitable for electric vehicles, as electric vehicles enter our lives. If we think that e-mobility consists only of electric vehicles, then we would be making a mistake. After all, there are many needs such as we need to charge … Read more
Sometimes the shocking effect of an earthquake has greater consequences beyond physical damage. In addition to visible damages such as cracking walls or breaking windows, fires, explosions and electric shocks that occur as a result of electrical panels falling over, cable systems breaking or short circuits can be one of the main causes of loss … Read more
After a century spent under the rule of fossil fuels, the world is breaking its course into a new era. The most symbolic carrier of this transformation is electric vehicles (EV – electric vehicles). As silence replaces exhaust fumes, this change on the roads means not only the evolution of engine systems, but also the … Read more
Electricity tariffsis determined in line with the Electricity Market Law No. 6446, the Electricity Market Tariffs Regulation and EMRA decisions. EMRA creates pricing mechanisms that are cost-based and include a reasonable rate of return for each component, taking into account the activities in the energy supply chain (generation, transmission, distribution and retail sales). Tariffs regulated … Read more
The lists prepared by Engineering News-Record (ENR) magazine, taking into account the data it receives in many fields every year, are seen as a great source of prestige for the construction industry. In its bulletin titled “Market Volatility Smooths Gains”, which was included in the “Top 250 Global Contractor” list published by Engineering News-Record (ENR) … Read more
Ensuring the reliability and efficiency of power grids is critical in modern infrastructure management. One of the most widely accepted techniques for assessing cable health. Very Low Frequency (VLF) testing; Detecting insulation deficiency is a basic method to prevent unexpected malfunctions and extend the operational life of cable systems. Power cables were traditionally tested with … Read more
In the TT system, the neutral point on the grid side is directly grounded. The grounding of the facility is carried out with a grounding electrode, independent of the network. Therefore, when there is a fault (e.g. phase contact with a device body), the fault current flows between the network ground point and the plant … Read more
Transformers are stationary electrical machines that allow us to obtain different voltage and current values from the other windings at the same frequency and the same power by means of electromagnetic induction by applying the alternating voltage to one of the windings. Transformers are generally used in energy transmission and distribution. In addition, there are … Read more
