Short circuit tests are conducted to evaluate the electrical safety of products, aiming to ensure protection against fire or shock hazards. Since 2006, with the acquisition of a 7.5 MVA transformer, INTEK has been performing short circuit tests. This specific area has become a source of great satisfaction due to the experience gained and the collaboration with prestigious companies and institutes, making it a fundamental pillar of INTEK’s electrical safety testing activities.
How a Short Circuit Test is Conducted
A short circuit test simulates a fault condition where two conductors with different voltages come into direct contact, causing a high current flow and potential damage. The importance of this test lies in its ability to evaluate the effectiveness of products in safely managing such situations, preventing severe accidents and explosions. During the short circuit test, the product’s responses are monitored, and any damage or performance anomalies are identified.
The INTEK Short Circuit Laboratory can verify the behavior and performance of electrical and electronic devices under fault conditions that can occur in the electrical network.
Short Circuit Tests: Industries and Reference Standards
Short circuit tests are widely used in various sectors, including consumer electronics, the automotive industry, and the field of electrical power distribution. The execution of short circuit tests is regulated by specific directives for each field, such as IEC 60947 for controlgear or IEC 61800-5 for variable speed motor drives. These standards establish test requirements and procedures, as well as evaluation criteria to ensure product compliance with industry regulations.
