The current edition is IEC 60947-6-1:2026 (Ed. 4.0, April 2026).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is an ATS (automatic transfer switch)?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is switching equipment that automatically transfers the load to an alternative source (usually a generator) when the mains power is interrupted, and transfers it back when the source is restored. ATSE, under IEC 60947-6-1, defines this function.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What is the difference between an open passage and a closed passage?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In an open-connection system, there is a brief interruption between the sources (open-close). In a closed-connection system, the sources remain in parallel for a very short time, and the transmission occurs without interruption.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Who performs the periodic inspection of the ATS\/transfer switchboard?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Periodic inspections of generators and transfer panels are carried out by authorized engineers at AES Innovation in accordance with relevant standards and regulations; transfer time, detection thresholds, and interlocking functions are evaluated.<\/p>","protected":false},"excerpt":{"rendered":"<p>An automatic transfer switch (ATS), which automatically switches the load to a generator (or alternative source) when the grid fails, is a critical component of an uninterruptible power infrastructure.
