The method of conducting a short circuit study involves examining an electrical system to gauge the size of fault currents flowing during a malfunction and contrasting the results with the device's intended grades and short circuit protection mechanisms.

For correct findings, VB Engineering’s short circuit analysis will perform a detailed engineering calculation by employing software including SKM, ETAP, and NEPLAN.

VB's Strategy For Success:

VB Engineering will gather installation information and develop an electrical model that includes the ability to endure short circuits following OEM specifications.

Fault current readings will be calculated and reported in the results using the defined model to calculate electrical short circuit values.

According to applicable IEC and IEEE 60909 international standards, we provide several short circuit analyses. The collection and digitalization of site data will be done using the VB Tantra app. Depending on the needs of the customer, SKM, ETAP, or Neplan will be employed for the short circuit analysis.

VB Engineering’s Progress With Prominent Principles: 

Level 1: Data Gathering

For the infrastructure, we conduct short-circuit investigations according to IEC 60909 international norms. The site's as-built state will be taken into account while computing and tabulating the findings of our short-circuit study.

The OEM short circuit enduring capability will be examined to the calculated etap or SKM short circuit analysis. Our devoted electrical crew will visit the location on time. They will gather the necessary information panel-by-panel, including switch gear ratings, relay settings, etc., and their corresponding photos for reference. Additionally, digitize the data so that the back-end staff may access it for additional study.

Our VB Tantra mobile application can handle all of this, from the source side to the load side.

Level 2: Construct A Single-line Diagram  

A crucial step that must come after the short circuit analysis seems to be the short circuit coordination research. The fault current study will decide the short circuit study inside this power system, and the etap or SKM short circuit analysis performed for the industry is generally accepted. These power system investigations, which include electrical short circuits, are also referred to as "three-phase short circuit studies" in various locales.

A single-line diagram would be a high-level schematic representation of the distribution of incoming electricity to equipment. Therefore, using the information gathered by our group of surveyors, our back-office squad will validate the information using the images that were apprehended.

Once all of the information is confirmed to be accurate based on the situation on the ground, they will start developing the diagram that demonstrates how all elements are electrically linked in reputable electrical software, including ETAP and SKM. Or, if one already occurs, it is changed under "customer needs" before being sent for additional examination.

Level 3: Results Tabulation And Computer Evaluation

This power system short circuit analysis is essential for figuring out the precise protection that the electrical network needs. You may download a sample short circuit study from our skill set for research purposes, and our staff can provide you with further tips on how to carry out precise short circuit studies in power systems.

The short-circuit currents at different locations in the system are computed using reputable computer programs, including SKM, ETAP, and NEPLAN, utilizing the system's gathered data as input and adding various faults, including three-phase faults, single-phase to ground faults, etc.

To compare the findings with the ratings of already-installed equipment in the system, the results are often compiled into a table. Issues are noted, and an official report will be written in conformance with international guidelines.

Keep in mind that VB Engineering will always be there for business throughout the process to correctly establish the ideal characteristics, ratings, and configurations of the power system protection devices following international standards.
