Web6 de mar. de 2024 · Jan 12, 2024. #16. For a typical high voltage current transformer for a 500 kV transmission line, current ratio may be 3000:5. If 3000 A flows on the transmission line, 5 A flows on the CT secondary side. If a typical resistor at the CT secondary side is 0.2 ohm, you see 5 A x 0.2 ohm = 1 V on the secondary side. WebNo-Load test or Open-Circuit Test: The no-load test of an induction motor is similar to the open-circuit test of a transformer. The motor is not connected from its load, and the rated voltage at the rated frequency is applied to the stator to run the motor without a load. The 2-wattmeter method measures the input power of the system.
