In high voltage transmission, this admits of much smaller transformers being built for high pressure than possible with the delta connection.
The line supplies three phase currents at high voltage direct to the field of the induction motor and drives it, generating in it currents at a lower voltage depending on the ratio of the windings.
This form of transformer is used to transform a low voltage current into a high voltage current.
A high voltage is necessary in order to cause the current to leap across the gap made by the separation of the electrodes.
By using a high voltage it may be sent hundreds of miles, but to use a current of that character in the cars, or shops, or homes, would be exceedingly dangerous.
If, for instance, the primary coil has a low voltage, the secondary coil will have a high voltage, or tension.
The gases are placed in transparent glass or quartz tubes at rather low pressures and a high voltage is impressed upon the ends of these tubes.
On connecting a high voltage to electrodes in each end, an electrical discharge passed through the residual gas making it luminous.
Marks contributed largely to the success of the enclosed arc by showing that a small current and a high voltage of 80 to 85 volts were the requisites for a satisfactory enclosed arc.
If there be only one incoming line and no high voltage bus, the line circuit breaker is generally non-automatic.
Stations with more than one bank of power transformers, a high voltage bus, and high and low voltage circuit breakers, may have both circuit breakers arranged to trip at the same time or one after the other.
In order to avoid the prohibitive expense ofhigh voltage insulation, the reactance coil is designed for the low tension circuit.
Continuous-current motors are, of course, subject to the same limitations as dynamos in the matter of capacity at high voltage, so that a series of motors must be employed to receive the high-pressure energy from the line.
Separately excited magnet coils make it easier to control the operation of the several dynamos, coils of low-voltage are cheaper to make than coils of high voltage, and the low voltage windings are less liable to burn out.
When fitted with a spark gap the high voltage, low frequency currents are converted into high voltage, high frequency currents.
If now we decide to generate this electrical energy at ten times as high voltageit will be necessary to transmit only one tenth as many amperes, or five.
This induces a secondary current in the whole coil which, because it passes through a very great number of turns, has a high voltage.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "high voltage" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
