Bierer-VDAH300

Analog Voltage Detectors - Bierer Meters

 (8)

The VDAO40C tests capacitive test points and direct contact voltages to 40kV line to ground (0-69kV phase to phase). The VDAO40P detects 0-40kV line to ground using proximity or direct contact. It also tests capacitive test points & secondary voltage on bare or insulated cables.
 
Both VDAO40 models have a 5-position selector switch which is calibrated for height above ground to compensate for capacitive coupling effects. These detectors include overload protection to 500kV.
 
The VDAO300 reads 2.4-300kV line to ground (4-500kV phase to phase). The VDAO450 reads 2.4-450kV line to ground (4-765kV phase to phase). Both meters use a single range Linear/Log ...

Bierer-VIAV300red

Voltage Indicators - Bierer Meters

 (4)

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 ...
