How is an electric current formed? Answer: The free electrons in the conductor move regularly and directionally under the action of the electric field force, and an electric current is formed. What are the indicators of power quality? Answer: Voltage deviation, voltage fluctuation and flicker, voltage sine wave distortion rate, frequency deviation. ...

1. Flashover fault: The industrial control cable is in a good insulation state at low voltage and will not have a fault. However, as long as the voltage value rises to a certain range, or a certain voltage continues to rise after a period of time, then it will instantly break through the insulator and cause flashover fault. 2. Long-term ...
