Is it possible to measure the leakage current of a 3-phase/3-wire or 3-phase/4-wire device?

Yes, the ST5540 Leak Current HiTester lets you choose the corresponding network and set the leakage current type to contact current (enclosure-enclosure). The proper settings will cause a network circuit to be connected between the ST5540’s T1 and T2 terminals (causing it to behave as an ammeter with a network). Connect the T1 and T2 terminals to locations at which you wish to measure the leakage current.
