RCD load is a kind of non-linear simulation load, which can be used to test power supply equipment such as data center generator set and UPS to understand its working ability with nonlinear load. Through the accurate detection of its output power and quality, it can avoid the failure to drive the load or cause pollution to the power grid in actual use, and ensure the safety of power supply.
With the more and more extensive application of electronic technology, from the electrical equipment used in our daily life to the equipment commonly used in industrial production, the traditional inductive load is no longer the main linear, but the main nonlinear load characteristics.
Most of the loads supplied by UPS are rectifier-filtered, and the input of UPS is rectifier-filtered. Therefore, a Reference non-linear load is developed in IEC standard and included in the appendix of the standard. Use this reference nonlinear load to test the UPS capability with nonlinear load.
