What is Contact Voltage?
A voltage resulting from
power system faults that may be
present between two conductive
surfaces that can be
simultaneously contacted by
members of the general public or
their animals. Contact Voltage
is not related to the normal
delivery or use of electricity,
and can exist at levels that may
be hazardous.
What is Stray Voltage?
A voltage resulting from
the normal delivery or use of
electricity which may be present
between two conductive surfaces
that can be simultaneously
contacted by members of the
general public or their animals.
Stray voltage is not related to
power system faults, and is
generally not considered
hazardous.
How
does Contact Voltage occur?
Contact Voltage can occur due
to deterioration of insulation,
damage to equipment from
accidents or construction, and
faulty workmanship.
When is
Contact Voltage the biggest
threat?
Contact Voltage is a concern
that requires attention and
intervention all year long.
Where
does Contact Voltage typically
occur?
Any surface which lies above
buried electrical infrastructure
can become energized.
Traditional utility assets such
as manhole covers and
streetlights present frequent
problems, however
non-traditional hazards
including sidewalks, fences,
storefronts etc. are commonly
energized and particularly
dangerous.
How can
Contact Voltage be controlled?
Mobile detection, capable of
thorough and rapid citywide
scans, presents a comprehensive
solution.
