The ratio of the number of turns on the primary coil of an electrical transformer to the number on the secondary, or vice versa.
- ‘On-site testing of turns ratio is an important basic measurement for power transformer diagnosis.’
- ‘The voltage ratios are equal to the turns ratios so we can just square the voltage ratios to get the impedance ratios.’
- ‘The effect of unequal turns ratios is approximately the same regardless of load current.’
- ‘Output voltage depends on turns ratios which are limited to plus or minus one turn.’
