Determining whether the Three Phases AC SPD is working properly is a comprehensive process involving many aspects. How to effectively make this judgment will be elaborated below.
First, observe the appearance of the lightning protector. The appearance of a normal lightning arrester should be clean and tidy, with no obvious damage or deformation. If signs of scorching, deformation or cracking are found, it may mean that the lightning arrester has been struck by lightning or has other faults and requires further inspection.
Secondly, check the status of the indicator light of the lightning protector. Most Three Phases AC SPDs are equipped with status indicators to indicate the working status of the lightning protector. If the indicator light lights up normally, it usually means that the lightning arrester is in working condition. If the indicator light does not light up or flashes abnormally, it may indicate that there is a problem with the lightning protector.
In addition, the working status of the lightning arrester can also be judged by measuring its electrical parameters. For example, parameters such as the resistance value, insulation resistance and leakage current of the lightning arrester can be measured. If these parameters are outside the normal range, it may mean that the lightning arrester is faulty or has degraded performance.
In addition, paying attention to the working environment of the lightning arrester is also an important factor in judging its working status. If the lightning arrester is installed in a harsh environment such as moisture, dust, or high temperature, its normal operation may be affected. Therefore, regularly checking the working environment of the lightning arrester to ensure that it is operating under suitable conditions is also an important step in judging its working status.
Finally, judge based on historical records. If there has been a record of the lightning arrester being struck by lightning before, or if the arrester has been used for a long time, its working status may need to be checked and tested more frequently. At the same time, you can also refer to the instructions and maintenance suggestions provided by the manufacturer to better understand the performance and usage of the lightning arrester.
To sum up, judging whether the working status of Three Phases AC SPD is normal requires comprehensive consideration of many aspects. By observing the appearance, checking the status of the indicator lights, measuring electrical parameters, paying attention to the working environment, and making judgments based on historical records, you can more accurately understand the working status of the lightning arrester, thereby ensuring that it can effectively protect the power system from lightning hazards.
