The main advantage is that it eliminates the need for leads connecting the two power grids (power sources), with a distance of up to 20m, and can pass through walls and partitions (panels), unrestricted by terrain or facility structure, improving safety.
Operation is convenient, requiring only one operator and one supervisor.
During operation, the instrument sends digital signals to the receiving end through a wireless transmission module, thereby reducing interference, minimizing errors, and greatly improving the instrument's performance.
In use, first operate the receiving device on the conductor of the power grid under test, then operate the receiving device on the conductor of the other power grid under test. If the phases of the two tested power grids are the same, the voice repeatedly prompts: “Phase
same”, if the phases of the two tested power grids are different, the voice repeatedly prompts: “Attention, phases are different”.
The insulating operating tube (material) uses the Sanqiu brand moisture-proof insulating tube produced by military enterprises, conforming to the EC/1C78 standard, with characteristics of moisture-proof, high voltage resistance, impact resistance, and bending resistance.

The insulating rod is made of epoxy resin, each rod is 2 meters long (each rod consists of two sections). The insulating rod is specified to be produced by professional manufacturers, and its length and test voltage comply with the International Electrotechnical Commission IEC60855 and the national standard GB113398-92 "General Technical Conditions for Insulating Rods for Live Working".
Reference Table for Power Frequency Withstand Voltage Test of Insulating Rods
Voltage Level Effective Insulating Length of Insulating Rod 1-Minute Power Frequency Withstand Voltage
10kV and below 700mm 45kV
35kV 900mm 95kV
110kV 1300mm 220kV
220kV 2100mm 440kV
The insulating rod should be regularly subjected to power frequency withstand voltage tests, and visual inspection should be conducted to ensure there are no scratches, cracks, or other abnormalities. Store in a dry and ventilated place.
