ABSTRACT

Testing the voltage tolerance curve (VTC) of equipment is the basis for cognizing and understanding the voltage sag. This paper compares the existing five test methods and proposes a new test method. This method is based on the idea of curve classification, and can measure the VTC of various sensitive equipment efficiently and accurately. This paper proves the superiority of the method by building a test platform and comparing the test accuracy and workload of each method through the measured data.
