Electrical Testing of Transformers<\/strong>
To assess the condition, we carry out electrical tests on oil and cast-resin transformers \u2013 either directly on-site or in our test field.<\/p>\n\n\n\n

Scope of testing:<\/strong><\/p>\n\n\n\n

    \n
  • Insulation resistance<\/strong> (HV\u2013ground, HV\u2013LV, LV\u2013ground)<\/li>\n\n\n\n
  • Winding resistance<\/strong> (high- and low-voltage winding)<\/li>\n\n\n\n
  • Transformation ratio<\/strong> incl. tap changers<\/li>\n<\/ul>\n\n\n\n

    Advantages:<\/strong>
    Early fault detection \u2013 increased operational safety \u2013 extended service life.<\/p>\n<\/div>\n<\/div>\n\n\n\n

          Grounding Kits <\/h3>\n\n\n\n

          Earthing and short-circuiting devices (EuK) are portable safety equipment that ensure safe potential equalization when working on electrical installations. They reliably protect technicians against dangerous residual voltages and short-circuit currents.<\/p>\n\n\n\n

            Testing requirements for EuK devices<\/strong><\/p>\n\n\n\n

              \n
            • Grounding and short-circuit devices are safety equipment and are subject to the requirements of the 'regular recurring testing<\/strong>.<\/li>\n\n\n\n
            • Untested or defective grounding and short-circuit devices pose a significant safety risk based on experience from the professional association.<\/li>\n\n\n\n
            • The obligation to test electrical equipment also applies to grounding and short-circuit devices.<\/li>\n<\/ul>\n\n\n\n

              Relevant legal regulations are:<\/strong><\/p>\n\n\n\n

              According to the Accident Prevention Regulation DGUV Vorschrift 3 \u00a7 5, electrical equipment must be tested at specific intervals. The timeframes must be set in such a way that potential defects, which are expected, are detected in time.<\/p>\n\n\n\n

              According to the Industrial Safety Ordinance (BetrSichV) \u00a7\u00a7 4 and 10, work equipment must be suitable and safely provided. If harmful influences are present, testing is required.<\/p>\n\n\n\n

              According to the Occupational Safety Act (ArbSchG) \u00a7\u00a7 4 and 9, workplaces must be safely designed. In hazardous work areas, appropriate safety measures and precautions must be implemented, such as recurring tests.<\/p>\n\n\n\n

              According to the electrical engineering standard DIN VDE 0105-100, section 5.3, recurring tests are required to maintain the proper condition, which also applies to EuK devices.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
