Distance To Voltage
Considerations
8
The information provided below can help you better understand the behavior
of the DV690’s alarms based on the distance you are from a variety of voltage
sources.
CAUTION
This information is intended for general reference only and is not meant to replace proto-
cols that you may have in place to ensure safety. Always proceed with caution and verify
the operation of the DV690 before each use.
Refer to Figure 8.1, below, for the examples provided in this item list.
• Residential meters (240 VAC): Distance between the DV690 and the resi-
dential meter is approximately 3.1 to 4 inches (8 to 10 cm) when the alarms
trigger.
• Medium voltage pad-mounted transformers (600 VAC): Distance be-
tween the DV690 and the transformer is approximately 10 inches (25 cm)
when the alarms trigger.
• Distribution pole (7.2 to 14.4 kV AC): Distance between the DV690 and
the distribution pole is approximately 2.6 to 5 feet (0.8 to 1.5 m) when the
alarms trigger.
• Transmission pole (69 kV AC or higher): Distance between the DV690
and the transmission pole is approximately 10.8 feet (3.3 m) when the
alarms trigger.
