The Greenlee IEP-DVI-5 (52074193) Underground Bushing Probe is designed for use with the DVI-100 and DVI-500 Series of digital voltage indicators. The probe is designed for direct insertion into exposed 15, 25 or 35kV loadbreak bushings (after connecting elbows have been removed and properly stored). The probe must be inserted directly into the bushing and remain free and clear of all surrounding surfaces. It is rated for use up to 21kV line-to-ground. This probe should also be used in metal clad switchgear or any other applications where grounded or other live conductors may be in close proximity to the conductor being tested. The IEP-DVI-5 can also be used to measure elbow test points with the DVI-500T and DVI-100T indicators.
