The equipment covered in this manual must be used and serviced only by competent,
trained personnel familiar with and following approved work and safety practices.
This equipment is for use by such personnel and this manual is not intended as a
substitute for adequate training and experience in safe procedures for this type of
equipment.
These instructions neither cover all details or situations in equipment use, nor do
they provide for every possible contingency to be encountered in relation to
installation, operation or maintenance. Should additional information and details be
desired or if situations arise which are not covered adequately for the user's purpose,
the specifics should be referred to Hubbell Power Systems, Chance
Before operating a CHANCE
understand, and follow these instructions. Keep these instructions in the device
case for future reference.
Do not allow universal fitting to touch any part of URD cabinet, to become grounded
in any other way, or to contact another phase as this will cause erroneous voltage
indication and could cause severe personal injury or damage to equipment.

- Page 2 Readings from the ARVI represent the class of voltage that is present on the line. The C403-3374 is designed to determine phase-to-phase voltage classes up to 69kV. The C403-3375 is designed to determine phase-to-phase voltage classes up to 500kV.
- Page 3 Ranges The approximate voltage ranges to provide indication of each of the voltage classes are as follows: C403-3374 ARVI ONLY C403-3375 ARVI ONLY Voltage Class Voltage Range Voltage Class Voltage Range 600V 480V to 900V 69kV 50kV to 109kV 1kV to 6.5kV...
- Page 4 Verify full unit function by contacting with a known energized high voltage source or with the appropriate Voltage Indicator Tester (C403- 3409 for C403-3374 ARVI and C403-3431 Voltage Indicator Tester for C403- 3375 ARVI). 2. Thread the hook probe into the end fitting of the ARVI and attach universal fitting to an insulated hot stick of proper length for system voltage involved.
- Page 5 If ever in doubt about interpreting ARVI reading under any circumstance, always assume circuit is energized and take appropriate safety precautions. Operation — Underground (URD) C403-3374 ONLY WARNING Do not allow universal fitting to touch any part of URD cabinet, to become grounded in any other way, or to contact another phase as this will cause erroneous voltage indication and could cause severe personal injury or damage to equipment.
- Page 6 1. Due to the close proximity of energized parts and grounded surfaces, probes must not be used when using the ARVI on live-front URD equipment because probes could either bridge from phase-to-phase or phase-to-ground or suffi- ciently reduce clearance to cause flashover. Therefore the probes must be removed from the tool.
