Depends on the frequency response characterisitcs of the transformer and its construction.
For mid frequency transients, it may work very well. But some solation transformers capacitively couple very high frequency spikes from input to output without significant attenuation. So you cannot use them by themselves without additional surge protection.
I prefer using a good transient surge protection like Furman's products better than an isolation transformer.
