RCD load is a nonlinear simulation load that can be used to test power equipment such as data center generators and UPS to understand its ability to work with nonlinear loads. By accurately detecting its output power and quality, it can avoid the inability to drive the load or pollute the power grid in actual use, and ensure power safety.
