AI Technical Summary
Traditional phase comparators are difficult to use in windy weather because the insulating rod swings violently and the contact hook cannot make stable contact with the power line.
A portable intelligent phase comparator was designed, which uses a clamping unit and a drive unit to achieve stable clamping of the line through the cross rotation of the clamp handle, and to make stable contact with the line through the contact terminal. Combined with protective components, it prevents damage to the signal transmitter.
Stable contact between the phase comparator and power lines was achieved even in windy weather, reducing the difficulty of testing and improving the convenience and safety of operation.
