Understanding CT Magnetization Curve Testing
The CT magnetization curve test evaluates the magnetic properties of a current transformer's core by applying increasing AC voltage to the secondary winding while keeping the primary circuit open. By recording excitation current as voltage rises, the test identifies the knee-point voltage-the critical point where the CT core begins to saturate. Accurately measuring this knee point ensures reliable CT operation for both metering and protection applications, preventing maloperation during faults.
How the Test Works?
Using Wrindu's automated test instruments, engineers gradually increase voltage to the CT secondary and monitor excitation current. Measurements around the knee-point voltage are recorded, then the voltage is reduced to demagnetize the core. This process provides detailed insight into CT performance, core health, and suitability for high-accuracy measurements.
