This meter of complex type of analogue and digital type has a peak for memory of
maximum instaneous value of the transient voltage orcurrent during the short
circuit or ground fault on the transmission and distribution lines. |

1.Normal voltage and current will be indicated by an along needle and then the peak
vlaue will be indicated on digital FAD(3Digital).
2.Demand of peak value will be indicated as memory(3Digital) the max one at only of
many peak values.
3.The rating of digital is same as analogue and full scale of is same as on analogue.
4.The peak value always turns on in the digital display, it is reset the peak value by
pressing the button.(push S/W)
5.When auxiliary power loss occurs, the peak value will be accumulated in S-RAM.
when auxiliary power returns, the peak value will be displayed in the digital display.
6.If an external reset terminal is connected on push button S/W, at inpossible
to reset on outside. |
