Bot Engineering Line Isolation Verifier

Bot Engineering’s Line Isolation Verifiers (LIVs) are lightweight rugged devices that have been specifically designed to detect the presence of AC potentials on unshielded conduc­tors. Our LIVs have a patented design utilizing a collimated signal fre­quency filter that provides maximum sensitivity to energized conductors that fall within 30 degrees of the instrument’s centre-line. This unique feature eliminates the adjacent conductor pick-up problem typically en­countered with other potential indicating devices. Thousands of Bot Engineering LIVs are extensively used in dozens of countries worldwide.

Line Isolation Verifiers (LIVs) are available in three models,
the LIV144, LIV500, and LIV500M. All three models cover a
voltage range of 2.4kV to 500kV and are identical except for
the voltage markings on the plunger scale. They all also have
a URD voltage position (Underground residential distribution)
that can be used to verify underground cables at load break
elbows.
The Line Verification Tester (LVT44) is similar to Line Isolation
Verifiers (LIVs) except that it has been optimized to operate at
a lower voltage range of 120VAC to 44KV.
Both the LIV and the LVT come with a removable hot stick
adapter that clips onto the units outer tubular surface.
An optional waterproof carrying / storage case is also available.
