Transient Voltages inLadder-Network Representations ofTransformerWinding and TransmissionLine

In thispaper,an analytical formulais introduced to determinethe transient voltage distribution inladder-network representations ofa transformer winding ora transmission linefollowing theimpact ofa stepfunction ofvoltage attheinput terminal ofthewinding ortheline. IndexTerms-- Analytical formula, laddernetwork, transient voltage, transformer winding, transmission line.
