The amount of water that flows under normal conditions is determined by the load on the turbines. Within limits, it makes little difference whether the reservoir behiiid the dam is large or small. This flow of water is comparable to the flow of load current in the distribution system in a factory.

On the other hand, if the dam breaks, the amount of water that will flow will depend upon the capacity of the reservoir and will bear little relation to the load on the turbines. Whether the reservoir is large or small will make a great difference in this case. This flow of water is comparable t o the flow of current through a short circuit in the distribution system.

The load currents do useful work, like the water that flows down the penstock through the turbine water wheel. The short-circuit currents produce unwanted effects, like the torrent that rushes madly downstream when the dam breaks.

There are three basic sources of short-circuit current: 1. Generators 2. Synchronous motors and synchronous condensers 3.

Generators are driven by turbines, diesel engines, water wheels, or other types of prime movers. When a short circuit occurs on the circuit fed by a generatar, the generator continues t o produce voltage because the field excitation is maintained and the prime mover drives the generator at substantially normal speed.

The generated voltage produces a shortcircuit current of a large magnitude which flows from the generator or generators to the short circuit. This flow of short-circuit current is limited only by the impedance of the generator and of the circuit between the generator and the short circuit. For a short circuit a t the terminals of the generator, the current from the generator is limited only by its own impedance.

Normally, synchronous motors draw a-c power from the line and convert electric energy to mechanical energy. However, the design of a synchronous motor is so much like that of a generator that electric energy can be produced just as in a generator, by driving the synchronous motor with a prime mover.

Actually, during a system short circuit the synchronous motor acts like a generator and delivers shortcircuit current to the system instead of drawing load current from it Fig. As soon as a short circuit is established, the voltage on the system is reduced to a very low value.

Consequently, the motor stops delivering energy to the mechanical load and starts slowing down. However, the inertia of the load and motor rotor tends to prevent the motor from slowing down. In other words, the rotating energy of the load and rotor drives the synchronous motor just as the prime mover drives a generator.

The amount of current depends upon the horsepower, voltage rating, and reactance of the synchronous motor and the reactance of the system to the point of short circuit. There is one major difference. The induction motor has no d-c field winding, but there is a flux in the induction motor during normal operation.

This flux acts like flux produced by the d-c field winding in the synchronous motor. The field of the induction motor is produced by induction from the stator rather than from the d-c winding.

The rotor flux remains normal as long as voltage is applied to the stator from an external source. However, if the external source of voltage is removed suddenly, as it is when a short circuit occurs on the system, the flux in the rotor cannot change instantly. Since the rotor flux cannot decay instantly and the inertia drives the induction motor, a voltage is generated in the stator winding causing a short-circuit current to flow to the short circuit until the rotor flux decays to zero.Yes, you have to be on the same home wifi connection.

That can occur only if the current is displaced from the zero axis, as shown in Fig. Yes, you have to be on the same home wifi connection.

In this illustration the current is a sine wave and is displaced 90' from the voltage wave and also i The amount of water that flows under normal conditions is determined by the load on the turbines.

The flux does last long enough to prodnce enough short-circuit current to affect the momentary duty on circuit breakers and the interrupting duty on devices which open within one or two cycles after a short circuit.
