s to oppose each other. The resultant voltagebetween the points a and b will then be zero, notwithstanding the fact thatfull voltage exists between the terminals of each transformer secondary.Therefore, if the points a and b be joined together no current will flow. If.however, instead of being… … Transformer No.z. Fig. 286. Connections for Transformer Heat Test the primary coils. Since each transformer is in effect short-circuited by theother, it follows that approximately twice the impedance voltage* of onetransformer impressed at C will cause full-load current to flow through theprimaries…
