The Vanguard EZCT-2000 can perform the current transformer (CT) excitation test, measure the CT winding resistance and CT current-ratio automatically

All of the EZCT-2000’s test leads can be connected to the CT output terminals (X1, X2, X3, X4 and X5), eliminating the need for lead switching during testing. Test voltage output is automatically raised and lowered by the EZCT-2000 without any operator intervention. With up to 2000 Vac excitation test voltage available, the EZCT-2000 can easily perform excitation tests on very large CT’s.
