1. It can be seen from the reaction time: it determines whether the lightning arrester can respond in time and quickly discharge the lightning current
High-voltage lightning arrester
2. It can be seen from the insertion loss: this refers to installing a lightning arrester. The impact of this lightning arrester on the line is as small as possible
Metal oxide surge arrester
3. It can be seen from the number of impact resistance: it determines the service life of the lightning arrester. Generally, the gas discharge tube will not decline after being left for a period of time. If you want to test its quality, you can use an adjustable high-voltage DC power supply to test it.
Generally, the quality of the lightning arrester is judged based on these three indicators. If the lightning arrester is very close to the electrical equipment, then (assuming the electrical distance L=0), then the residual voltage of the electrical equipment struck by lightning is equal to the residual voltage of the lightning arrester. The lower the residual voltage, the safer the protected equipment will be.
