Application
The current pulse instrument is used for testing earth fault indicators and short circuit indicators.
The instrument can be adjusted (infinitely variable) within the range of 10 and 1000 A.
The pulse duration is adjustable from 20 ms to 200 ms.
The adjusted current is displayed on a LCD-display.
The instrument is build robustly and thus suitable for application in the assembly. |

General Description
The current pulse instrument (1) is incorporated in a metal housing with the dimensions
(LxWxH) 300 x 210 x 300 mm.
The housing contains a power transformer, a variable-ratio transformer and the control. On the backside of the instrument (2) is the connection terminal for the short circuit cable (*).
Use
The instrument is adjusted according to the instruction manual to the wished current and pulse duration (confer backside).
Now the short circuit cable is led through the frame of the sensor. By pressing the button, current pulses can be switched onto the tested indicator.
The accuracy of the display is +/- 10%. If more precise values are needed, it is recommendable to measure the adjusted current with a clip-on ammeter. |
