fast drop of the voltage on the grid, so called Voltage Dips, could bring transformers into core saturation, depending the phase angle of the dip. Core saturation brings inrush currents and leads to fuse tripping. A TSRL avoids the core saturation and the fuse tripping. Medical equipment must have been proved with voltage dips. EMV Norm: EN 60601-1-2 . Without a TSRL, they cannot widtstand this test. With a TSRL they pass.
