The invention relates to an intelligent tester for a transformer coil turn-to-turn short circuit. The intelligent tester for the transformer coil turn-to-turn short circuit detects whether a short circuit occurs or not between shunt-wound adjacent turns in the winding process of a transformer coil. The tester comprises a control module, a routing inspection module, a sound-light alarm module and a power supply module. The control module comprises a single chip microcomputer, the input end of the control module is connected with the power supply module, and the output end of the control module is connected with the sound-light alarm module; the routing inspection module comprises at least one relay control circuit connected with the output end of the single chip microcomputer, at least two terminal blocks used for having access to wire turns are arranged at the input end of the single chip microcomputer, and the other end of the relay control circuit is connected with a corresponding terminal block which is utilized to apply test voltage to a corresponding wire turn. A wire turn-to-turn short circuit fault can be timely detected in the winding process, the position of a short-circuit wire turn is displayed in a sound-light alarm mode, the wire tune is timely replaced once a problem is found, thus cost of manpower and material resources is saved, and production efficiency is improved.
