Fundamentally, any transformer on earth has input and output powers.

In these transformers, the input power is equivalent to the output power. Nevertheless, this transformer is not feasible in reality.

In the case of the no-load condition, the value of the copper losses is zero.<\/span><\/p>\n<p>By putting the variables in the mentioned equations, we have<\/p>\n<p style=\"text-align: center;\"><span class=\"katex-eq\" data-katex-display=\"false\">\\eta=(\\frac{input~power-iron~loss-copper~loss}{input~power})\\times100<\/span>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><span

suppose that is 10 KVA.<\/p>\n<p>Therefore,<\/p>\n<p style=\"text-align: center;\"><span class=\"katex-eq\" data-katex-display=\"false\">\\eta=(\\frac{1000-1.2-10}{1000})\\times100=98.88\\%<\/span>\n<p>&nbsp;<\/p>\n<p>Accordingly, the higher the load, the higher the copper losses, and the lower the efficiency.<\/p>\n<p><span data-preserver-spaces=\"true\">Considering this fact, we can conclude the maximum efficiency that the transformer can reach.<\/span><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>So, We Can Determine the Equation of Maximum Efficiency of Transformer:<\/strong><\/p>\n<p><span data-preserver-spaces=\"true\">Assume

transformer condition.<\/p>\n<p>Furthermore, efficiency will be highest if the denominator concerning the changeable copper losses is equated to zero.<\/p>\n<p>We can presume that we will obtain maximum efficiency if copper losses (P<sub>c<\/sub>) are equivalent to iron losses (P<sub>i<\/sub>).<\/p>\n<p>So,<\/p>\n<p style=\"text-align: center;\"><span class=\"katex-eq\"

data-katex-display=\"false\">\\eta_{max}=\\frac{output~power}{output~power+2P_i}\\times100\\%<\/span>\n<p>&nbsp;<\/p>\n<p>Besides, copper losses are:<\/p>\n<p style=\"text-align: center;\"><span class=\"katex-eq\" data-katex-display=\"false\">P_C=x2P_C<\/span>\n<p>&nbsp;<\/p>\n<p>where P<sub>c<\/sub> is the full load coper losses.<\/p>\n<p>In the condition of maximum efficiency, we have:<\/p>\n<p style=\"text-align: center;\"><span class=\"katex-eq\" data-katex-display=\"false\">P_i=X2\\times P_c<\/span>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><span class=\"katex-eq\"

transformer?<\/p>\n<p>Repeatedly, we will explain in numbers as is the best proof to confirm the facts:<\/p>\n<ul>\n<li>Assume there is a transformer with a power of 100 kVA and the iron losses are 0.2 kVA, and in the secondary coil, the current is 8 amperes with a lag power factor of 0.8, next:<\/li>\n<\/ul>\n<p style=\"text-align: center;\"><span class=\"katex-eq\"

current is 8 amperes with a 0.6 lag power factor, we have:<\/p>\n<p style=\"text-align: center;\"><span class=\"katex-eq\" data-katex-display=\"false\">(P_c)~Coper~losses=V2\\times I2\\times Cos \\Phi=220\\times 8\\times 0.6=1.06~KVA<\/span>\n<p style=\"text-align: center;\"><span class=\"katex-eq\"

constant.<\/p>\n<h3><em>The Fifth One <\/em><\/h3>\n<p>Is the efficiency of the transformer assessed and examined only instantly?<\/p>\n<p>After distinguishing the above facts, we can recognize that the transformer efficiency is changeable all the time, but will the efficiency be examined and recorded every minute, hour, day, or month?<\/p>\n<p>As we described earlier, this efficiency has various factors. Most essential, the download and the loading are not solidified; we have to manage a comprehensive study every hour to create a daily report to analyze the transformer efficiency.<\/p>\n<p>But how is the transformer efficiency measured throughout the day? The answer is sincere and lies in the following equations:<\/p>\n<p style=\"text-align: center;\"><span class=\"katex-eq\" data-katex-display=\"false\">\\eta=(\\frac{input~power-iron~loss-copper~loss}{input~power})\\times 100\\%<\/span>\n<p>&nbsp;<\/p>\n<p>Note that iron loss is solidified all day, and Copper loss varies according to the loading condition<\/p>\n<p style=\"text-align: center;\"><span class=\"katex-eq\" data-katex-display=\"false\">\\eta~(for~24~hour)=\\frac{(input~power-iron~loss)-(\\Sigma~copper~loss~for~24~hours\/24)}{input~power}\\times 100\\%<\/span>\n<p>&nbsp;<\/p>\n<figure id=\"attachment_4301\" aria-describedby=\"caption-attachment-4301\" style=\"width: 572px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-4301 size-full\" src=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/01\/Figure2-1.png\" alt=\"transformer efficiency\" width=\"572\" height=\"310\" title=\"\" srcset=\"https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/01\/Figure2-1.png 572w, https:\/\/www.linquip.com\/blog\/wp-content\/uploads\/2021\/01\/Figure2-1-300x163.png 300w\" sizes=\"(max-width: 572px) 100vw, 572px\" \/><figcaption id=\"caption-attachment-4301\" class=\"wp-caption-text\">The variation of transformer efficiency with respect to load current (Reference: <strong>electrical4u.com<\/strong>)<\/figcaption><\/figure>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><strong>Conclusion<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>We have comprehensively discussed the transformer efficiency and the way of its calculation.
