Recent developments in kilovolt-ampere metering

The problem of measuring kilovolt-amperes power factor has received considerable attention from the rate maker and the electrical engineer during the last few years. This paper describes two late developments in kv-o. demand meters. One meter is of the indicating type and indicates total kw. hours, kw. demand and kv-a. demand. The other meter is of the recording type and gives a record of kw. demand kv-a. demand, kw. hours, and kv-a. hours.
