Description
The 2DG/2DH Cable-type Short-circuit Fault Indicator (Photoelectric Display) is mainly applied to ring main units and box-type substations. Featuring a compact size, it allows for easy installation. When a short-circuit fault occurs on the line, the red LED will light up to indicate the fault location.
Installation Method
Remove the U-shaped hoop, pass the cable through the hoop, refit the hoop, and then tighten the bolts to complete the installation.
Note
Its functional benefits, technical specifications and working principle are identical to those of the HLA-2DX.
