Radial systems include duplicate and throwover systems. The type of construction: overhead or underground. DESIRED FEATURES Electrical energy may be distributed over two or more wires. The principal features desired are safety; smooth and even ﬂow of power, as far as is practical; and economy. Safety The safety factor usually requires a voltage low enough to be safe when the electric energy is utilized by the ordinary consumer. Smooth and Even Flow of Power A steady, uniform, nonﬂuctuating ﬂow of power is highly desirable, both for lighting and for the operation of motors for power purposes.
The resistance of the elements involved is practically constant; hence current will vary directly as the applied voltage. The effect of reduced voltage and accompanying reduced current is merely to cause a corresponding reduction in the heat produced or a slowing down of the operation of the appliance or device. While voltage variation, therefore, is not critical, it is usually kept to small values since very often the smaller devices are connected to the same circuits as are lighting loads, although hot water heaters, ranges, and other larger loads are usually supplied from separate circuits.
Welders Welders draw very large currents for very short intermittent periods of time. They operate at a comparatively low voltage of 30 to 50 V, served from a separate transformer having a high current capacity. Larger welders may employ a motor-generator set between the welder and the power system to prevent annoying voltage dips. The power fac- 42 Electrical Distribution Engineering tor of welder loads is relatively low, varying with the load. The timing of the weld is of great importance and may be regulated by electronic timing devices.
