Working Principle
The High Voltage Digital Display Voice Phase Verifier obtains signals from high-voltage lines through inductive coupling, and then uses internal signal processing circuits for phase comparison. The instrument can measure the frequency and phase angle of two lines, and transmit this data wirelessly to the receiver. Operators can read the data on the receiver's display and obtain key information through the voice broadcast function.
Usage Steps
Preparation: Check that the instrument is intact and ensure sufficient battery power.
Set Frequency: Set the corresponding frequency range according to the actual line conditions.
Install Transmitter: Fix the transmitter on the high-voltage line to be tested, ensuring good contact with the line.
Receive Signal: Turn on the receiver at a safe distance to receive data sent by the transmitter.
Read Results: Observe the indications on the receiver screen and record frequency and phase information.
Determine Phase: Judge whether the two lines are in phase based on the displayed phase angle.
Voice Prompt: Confirm the phase relationship according to the voice broadcast.
Application Scenarios
New Line Grid Connection: Phase verification before connecting new high-voltage lines to the existing power grid.
Line Renovation: Phase confirmation when renovated lines are reconnected to the power grid.
Fault Troubleshooting: Use the High Voltage Digital Display Voice Phase Verifier for troubleshooting when phase disorders occur in the power grid.
Daily Maintenance: Regularly check the phase of lines to ensure stable operation of the power grid.
Usage Case
A power company used the High Voltage Digital Display Voice Phase Verifier for phase verification when connecting a new 110kV high-voltage line to the existing power grid. Through precise measurement by the instrument, it was confirmed that the new line was in phase with the original line, avoiding potential safety accidents caused by phase errors.
Conclusion
The High Voltage Digital Display Voice Phase Verifier, with its advanced technology and excellent performance, plays an important role in grid connection operations of power systems, not only improving operational efficiency but also greatly enhancing the safety and reliability of power grid operation.
