Description

Vektormesser mit eingebauten Vor- und Nebenwiderständen Unter :dem Namen Vektormesser ist ein universelles Meßgerät für präzise Wedhselstrommessungen aller Art bekanntgeworden. Ein wesentlicher Bestanidteil des Geräts ist ein kleiner meca.-niischer Meß:gleidhriehter, der von einem Synchronmotor angetrieben wird. Seine Kontaktzeit ist von o bis 36o elektrischen Graden einstellbar. Um die Handhabung des Geräts für Strom-und Spannungsmessungen möglichst einfach zu gestalten, sind Vor- und! Nebenwiderstände eingebaut. Bei diesen Widerständent i,st ein Formfaktor von i, i i für die übliche Sinusform der Spannungs- und Stromkurven berücksichtigt undi eingeeicht. Dadurch ist aber :die Verwendung des Vektormessens auf Wechselstrom:mes,sungen beschränkt.Vector knife with built-in series and shunt resistors Below: the Name vector meter is a universal measuring device for precise Wedhsel current measurements became known of all kinds. An essential part of the device is a small one meca.-Niischer Mess: smoothly rotated, which is driven by a synchronous motor. Its contact time is adjustable from 0 to 36o electrical degrees. About the handling of the device for current and voltage measurements are to be designed as simply as possible Before and! Shunt resistors built in. With these resistors there is a form factor of i, i i taken into account for the usual sinusoidal shape of the voltage and current curves undi calibrated. As a result, however: the use of vector measurement on alternating current: mes, sungen limited.

Um das Gerät auch: für präzise Gleichstrommessungen verwenden zu können, wird erfindungsgemäß auf der Skala des Drehspulins,tru:ments, mit dem die Kontaktzeit festgelegt wird, eine Marke für diejenige Kontaktzeit vorgesehen, die es ermöglicht, die ei@.ngebauten Vor- und Nebenwiderstände ohne Änderung der Meßbereidhhe statt mit Weohseltstrom mit Gleichstrom zu benutzen: Dadurch wird es auf einfache Weise nur durch Umstellung der Kontaktzeit möglich, die ein, gebauten Vor- und Nebenwiderstände mit den gleichen Meßbereichen wie bei Wechselstrom auch bei G1eiehstrom @benutven zu können. Dazu ist eine Kontaktzeit von notwendig. Der Faktor i, i r ist, wie schon oben erwähnt, der Formfaktor dier Sinuswelle und muß bei Gleichstrommessungen durch entsprechende Verringerung der Kontaktzeit rückgängig gemacht werden. Auf diese Weise gelingt es, aus dem Vektormesser einniver@ahgerät für präzise Gleich- und, WechGelstrommessungen, zu machen.In order to also be able to use the device for precise direct current measurements, a mark for the contact time is provided on the scale of the rotating coil, tru: ments with which the contact time is determined, Using shunt resistors without changing the measuring range instead of Weohseltstrom with direct current: This makes it possible to use the built-in series resistors and shunt resistors with the same measuring ranges as with alternating current also with direct current by simply changing the contact time. There is also a contact time of necessary. As mentioned above, the factor i, ir is the form factor of the sine wave and must be reversed in the case of direct current measurements by reducing the contact time accordingly. In this way it is possible to turn the vector knife into a level device for precise direct and alternating current measurements.
