... the rectified cur- rent connected to the rectifier cathode and the secondary winding of the transformer , and a single device for protect- ing the rectifier and transformer against both internal short circuits and overloads on the ...
... a rectifier which was initially at room temperature which was then cooled slowly to the temperature of liquid nitrogen . The resulting current was measured by placing in series with the rectifier a 25 ohm resistor calibrated against a ...
... the rectifier works . There is no such limit to rating as there is in the converter or any other electromagnetic machine as in flux and current densities . The amount of current a rectifier will give depends largely on local ...
... the rectifier as necessary and check again a few days later . Two or three checks and adjustments should be sufficient for the rectifier to give the proper voltage . Routine Inspection As stated above once the rectifiers are adjusted ...
... the rectifier is actually damaged , it should be returned to the signal shop for repairs . Before removing the rectifier , determine that the proper ac voltage is being supplied to the rectifier by checking the voltage across the ac ...
... the rectifier as necessary and check again a few days later . Two or three checks and adjustments should be sufficient for the rectifier to give the proper voltage . Routine Inspection As stated above once the rectifiers are adjusted ...
... the rectifiers are connected together with tie - feeder circuit breakers installed at locations between the rectifiers as shown in figure 36 , or zones of protection are provided to detect short circuits that may occur . For example ...
... the rectifiers . The principle of the latter is as follows : - On a built - up ring A ( fig . 1 ) there are two windings as shown . These windings , fed at the points B and C by a single - phase current , produce a closed magnetic field ...
... the rectifiers were protected by their cases with the equivalent of at least 254 μm ( 10 mils ) of copper shielding , calculations from proton range - energy curves for copper showed that 22 - MeV protons were the lowest proton energy ...
... the rectifiers are now provided with a 15 per cent tap , which gives a considerable extra range . When connecting the battery care must be taken to be sure that the positive or ( plus ) binding post on the rectifier is con- nected to ...
