A 24 volt 1 amp transformer will have a primary current of around ma (full load), the magnetizing current (no load current) will be 20 ma or less. This can be measured with a DVM or VOM. If you think the transformer has excessive magnetizing current due to shorted windings, you might connect a resistor of 1, ohms (2 watt) in series with the transformer’s primary.
