For grounding and interference measurements we need a transformer that is able to supply 120 V at 284 A in one phase, without stressing the power supply with unbalanced load. To get detailed measurements we also need graded, smaller voltages, which are adjustable with a toggle. The transformer has to be fused in case of a short circuit, it needs to do a safe galvanic separation and it should be a distinct device in our test laboratory.
