MV Voltage Indication System DXN2-T
DXN2-T MV voltage indication systems indicate the voltage presence on M.V. cubicles （switchgear） by being installed on the capacitive dividers.
Features of MV Voltage Indication System DXN2-T
* 3 phase live voltage
indication system
* Overvoltage
protection
* With the extra terminal for
interlocking signals output. Can work with the lock indicating units (such as
DXN2-Q) to realize lock indication
* Wide-range: 3kV-
40.5kV
* Working frequency:
50/60Hz
* Threshold values for
voltage presence indication: U>0.40 x Unmin
* Threshold values for
voltage absence indication: U<0.15 x Unmax
* Threshold values for
over-voltage protection: <0.30 x Unmin
* Divider capacitance 18pF or be specified
by buyer
* Temperature range
-25°C to +40°C
* Insulation strength:
AC 2kV, 1min
* Product dimensions
(L×W×D) 130x30x168mm
