A <strong>100 kVA transformer<\/strong> has the capacity to deliver up to 100,000 volt-amperes of apparent power to the load.<\/p>\n\n<p>However, to convert this into actual usable power (in kilowatts), we need to consider the <strong>power factor (PF)<\/strong> \u2014 a measure of how efficiently the current is being converted into useful work. In most industrial settings, a typical power factor is <strong>0.8<\/strong>. Therefore:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Load Capacity (in kW)<\/strong> = 100 kVA \u00d7 0.8 = <strong>80 kW<\/strong><\/li>\n<\/ul>\n\n<p>So, a 100 kVA transformer can support up to <strong>80 kW<\/strong> of real power under typical conditions.<\/p>\n\n<h2 class=\"wp-block-heading\">Applications of a 100 kVA Transformer<\/h2>\n\n<p>Transformers with a 100 kVA rating strike a balance between affordability and utility. Here are common scenarios where they&#8217;re used:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Commercial Buildings<\/strong>: Powering HVAC, elevators, lighting, and office equipment.<\/li>\n\n<li><strong>Small to Medium Industrial Plants<\/strong>: Operating CNC machines, compressors, or packaging lines.<\/li>\n\n<li><strong>Agricultural Facilities<\/strong>: Running irrigation pumps and storage systems.<\/li>\n\n<li><strong>Integrace obnoviteln\u00fdch zdroj\u016f energie<\/strong>: Used in solar or wind energy systems for stepping up\/down
