The cable identification instrument must ensure the accuracy of the data. On the one hand, we need the cable identification instrument to have good accuracy. If the accuracy is not enough, we will use it in vain. If it is inaccurate, it will affect the later period. In addition to the accuracy, the cable identifier must ensure the accuracy of the data. On the one hand, we need the cable identifier to have good accuracy. If the accuracy is not enough, we will use it in vain. If it is inaccurate, it will affect the later time. In addition to accuracy, it is to ensure the service life.
Using ordinary voltage and current ratio meter type grounding resistance meter (commonly known as“earth shaker”) When measuring the grounding resistance, the grounding down-conductor should be separated from the iron tower through the grounding device of the iron tower and measured; the grounding down-conductor should be separated from the lightning protection wire from the top of the pole through the grounding device of the non-prestressed reinforced concrete pole. Measurement. In the initial state of the system, press the setting button of the DC resistance tester to enter the setting function state, set the material option to unknown, the measurement mode to resistance, the working mode to standard, and the measurement speed to standard, press the return key to return to the initial state of the system. The above is the content of the cable identification instrument introduced to you today. I hope it can bring you some help. Thank you for your reading. If you have any needs, please contact us.
