- 1No-load test yields rotor copper loss; blocked-rotor test determines air-gap power.
- 2No-load test determines total leakage reactance; blocked-rotor test gives mechanical losses only.
- 3No-load test gives magnetising reactance and stator resistance; blocked-rotor test gives rotor reactance and magnetising current.
- 4No-load test provides core-loss and magnetising components; blocked-rotor test gives equivalent resistance and leakage reactance.✓
Correct answer
No-load test provides core-loss and magnetising components; blocked-rotor test gives equivalent resistance and leakage reactance.
