NEW PLANT EQUIPMENT Thermal Demand Melert E224 Built into tiib samb cask with standard watt-hour meters, the new thermal ampere- demand meters provide low-cost, compact unita that can he used by utilities on single-phase or polyphase systems for cer tain Industrial end commercial installations where kva demands are incorporated into the rating. They are not intended for larger industrial metering. Ampere demand is measured in these meters by heating of e bi-metallic element with current-carrying heaters. The read ings may be converted to kva demand by Meehanleal-Drlve Turbine E222 multiplying by a constant assumed voltage. The low initial and maintenance coat of Tyfk DP I* a new imall mechanical-drive turbine with retinge ranging from 10 to 1200 hp and epeede (root 1000 to 5000 rpm. Available In three single-stage frame eitea with a 15 in., 20 In. and 25 in. wheel, Type DP embodies such features of large tur> such devices permit! application to imatler loads than ean be justified with the more elaborate mechanical integrating device*. Five types are available, making the meter suitable for single-phase; 3-phase, 3wire service; (or networks consisting ol bines at hydraulic governing for wider speed range and more aecnrate control and pressure oiling of bearings. It can be ap- two phases and neutral of a 3-phaae, 4-wire service; for 3-phsse, 4-wire delta service; and for 3-phaae. 4-wire wye sendee.

The new oil-relayed governing system gives superior performance, according to maker. Range of speed adjustment has been Increaaed to 30%: speed regulation has been reduced to 6%. More pens ere inclosed end governing system Is completely Incased In an oil atmosphere. A new bat* ancet] valve design ia uaed for the governing valve and combined trip-throttle valve. With this design less force is required to operate valves ami given tita valve can handle larger steam flows. These valves ore com bined in one assembly. Maintenance is made easier by accessi bility of individual components, such as the oil cooler, oil pump, and steam and oil strainers. The great majority of parts are Interchangeable on all Type DP frame sites. Spare parts kits, with parts applicable to these standard turbines, are available.
