VBI-15 Voltage Break Indicator is activated when voltage level drops below 2.5kV line to ground. It is overload protected to 115kV.
AV40 indicates on direct contact to capacitive test points or 120-600V secondaries. It also does non-contact sensing on 7.2/14.4/20 kV URD and 2.4/7.2/ 14.4/20/40 kV OH. A 12- position rotary switch selects function & range.
VIAV300 is a proximity & direct contact voltage indicator with 240V & 2.5/7.5/15/30/ 40/70/140/300 kV ranges selected by a 12-position rotary switch.

  • Super bright LEDs & ultra loud horn
  •  Detects line to ground voltage
  •  Activation threshold meets ASTM requirement
  •  Standard 9 Volt battery
  •  Test position (except VBI-15)
