Before revision: Other uses Along with the standard application the growler can be used to: test series and interpoles (commutating) fields from a DC motor to determine phasing and polarity in multiwinding armatures to test rotors in rotating frequency changers, as well as in wound rotors to test shorts between turns in taped coils before installation into an armature or a stator as a low voltage isolation transformer as a high voltage autotransformer bucking or boosting for numerous tests on various types of equipment for preheating or baking armatures and rotors.
