Rosa and M. G. Lloyd. Alternating-current transformers are so useful in the measure-ment of current and potential, by reducing the current or potentialthat must be applied directly to the instruments, that they havebeen extensively used in engineering work for the measurement ofcurrent, voltage, and power, not only for the heaviest currentsand highest potentials, but also for currents and potentials of mod-erate values. Such transformers, when properly constructed, cansafely be in connection with precision voltmicters, am-meters, and wattmeters for measurements of considerable accu-racy. Indeed, if the constants of the transformers have beenaccurately measured, the precision of the results will dependchiefly on the indicating instruments, for the transformers them-selves are more perdetermi61301909116116rosa
