These fuses serve as a protection to the alternator in case of a short circuit at the main switch.
Its efficiency is less than for synchronous converters, and the danger of reaching double speed in case of a short circuit on the direct current side is very great.
First rush of current from alternator when short circuited, showing unsymmetrical current wave, also wave of field current caused by short circuit current in armature.
What should be done if a dynamo become reversed by a reversal of its field magnetism due to lightning, short circuit, or otherwise?
This sets up a "short circuit," and the zincs are consumed whether the battery is in action or not.
Should the battery be all right, and still none of the bells ring, a break or bad contact, or short circuit in the main wires near the battery may be the cause of the mischief.
When this occurs, it points to an electrical leakage, or short circuit, and this, of course, rapidly exhausts the battery.
It is therefore essential that the switches shall be able to break not only their normal current, but also greatly increased current that would flow if a short circuit or partial short circuit occur.
What means are employed to limit the value of a short circuit current?
If it is not required to use the cell at once, it may be placed on short circuit for a time and allowed to form its own zinc sulphate.
As a result, the internal resistance of the cell is small and the current which it will give on a short circuit is correspondingly large.
What the farmer would call a short cut the electrician calls a short circuit, and a short circuit is often a more convenient way of cutting off a current than a switch which interposes resistance.
In case of short circuit in the line the motor acts as a generator and thus increases the intensity of the short circuit.
The pressure at the terminals of the coil D is alternating; hence the latter, on account of its self-induction, does not act as a short circuit to the armature.
If any cell read low, it should be cut out and examined to see if any material has been introduced which would cause a short circuit.
Wooden moulding must not be used in concealed or damp places, nor be placed directly against a brick wall where sweating may introduce moisture that may ultimately cause a short circuit.
A Short Circuit We said a few paragraphs back that under no conditions must two bare wires leading from electric mains be permitted to touch each other, without some form of resistance being interposed in the form of lamps, or other devices.
The amount of electricity flowing through a short circuit is limited only by the fuse protecting that line; and since there is no substance known that can withstand the heat of the electric arc, short circuits must be guarded against.
Danger of fire from an electric current comes from the "short circuit," partial or complete; and it is against this danger that the rules guard one.
Thus with a short circuit of small external resistance, the strength of the current will be increased by increasing the size of the plates, or by joining the cells in multiple arc, but not in series.
This is called a short circuit because there is little or no resistance, and it provides the current with an easy path to escape.
You will also remember that you learned that when electricity took a short cut to get away from its proper path it was called a short circuit.
Such a result is very desirable in order that the entire service of a transmission system may not be interrupted every time there is a fault or short circuit on one of its distribution lines.
An effort was made to so adjust the sizes of the fuses in this transmission system that in case of a short circuit in distribution lines at Buffalo only the fuses in the sub-station would be blown, leaving those at Niagara entire.
A short circuit in the primary is caused by the insulation of the coils becoming defective and allowing the bare copper wires to touch each other.
A short circuit in the regulator winding is indicated by failure of the apparatus to regulate properly, and sometimes, though not always, by the heating of the regulator coils.
The remedy for a short circuit is to reinsulate the defective parts.
A short circuit, or trouble of any kind on this light might put the whole emergency system out of operation.
If this were not done, there would be a short circuit at the time of starting or striking the arc.
A short circuit on one lamp would put out a group of one hundred as quickly as it would ten.
If the separators are in good condition, a short circuit is unlikely to occur.
A cell in this condition can be repaired by removing the element and clearing the short circuit.
I heard him discussing the origin of a fire that had taken place in the town a few days before, and, as is usual in these days, it was said to have been due to a short circuit in the electric wires.
A short circuit is when--when--oh yes, when it is only a very short way from the electric lamp to where the wire is joined on to the cable.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "short circuit" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
