The measurement of power by a-c to d-c transducers requires that the operations of multiplication and integration be performed. A new transducer has been worked out in which multiplication is obtained by sum and difference squaring and integration plus averaging by use of capacitors and d-c instruments. This transducer is especially adapted to the measurement of power on circuits up to 13.2 kv line-to-line by use of hook-on current transformers.
