Los consumidores comerciales e industriales son vulnerables a las perturbaciones en las redes de distribución. Una solución a esto es utilizar los sistemas de alimentación ininterrumpida (UPS). Sin embargo, esto puede tener otros impactos en el sistema eléctrico. Este documento describe los principios fundamentales del funcionamiento del sistema UPS. Además, el trabajo presenta pruebas en dos UPS para verificar la calidad de la energía suministrada al sistema que alimenta el UPS. Para ello, se registraron el factor de potencia, el factor de desequilibrio de tensión, la variación de frecuencia y la forma de onda de tensión y corriente debido a la presencia de armónicos. Este documento también muestra la importancia de implementar un programa de etiquetado de UPS.
