The following calculator will determine the transformer’s turns ratio using either the primary and secondary voltage or current. At no load, voltage and turns ratios are equal. If the secondary winding has fewer turns than the primary, a lower voltage will be induced in the secondary. The turns ratio can be measured experimentally using a transformer turns ratio tester. The power output of a transformer, barring negligible resistance, is the same as its input, maintaining energy continuity. The transformer calculator calculates the primary and secondary full load current, and turns ratio, of a single or 3-phase transformer. Find the turn ratio of the transformer. where. Solved Problems on Turn Ratio. It also determines the turns ratio and type of transformer. The amount of voltage induced in each turn of the secondary winding will be the same as the voltage across each turn of the primary winding; this is referred to as the transformer turns ratio. Since the direct measurement techniques RF transformer turns ratio is defined as the ratio of the number of secondary turns to the number of primary turns (Ns/Np) or the ratio of the number of primary turns to the number of secondary turns (Np/Ns). Given data N p = 400 N s = 100. We can represent it using this equation: [latex] \frac{N_p}{N_s} [/latex] Here: (N_p) is the number of turns in the primary coil.
