The Difference Between Surge Protector And Lightning Arrester

Lightning arrester
1. Lightning arresters have multiple voltage levels, ranging from 0.38KV low voltage to 500KV ultra-high voltage, while surge protectors generally only have low-voltage products;
2. Lightning arresters are mostly installed on the primary system to prevent direct intrusion of lightning waves, while surge protectors are mostly installed on the secondary system. They are supplementary measures after the lightning arrester eliminates the direct intrusion of lightning waves, or when the lightning arrester does not eliminate the lightning waves completely;
3. Lightning arresters are used to protect electrical equipment, while surge protectors are mostly used to protect electronic instruments or meters;
4. Since lightning arresters are connected to the primary electrical system, they must have sufficient external insulation performance and are relatively large in appearance, while surge protectors can be made very small in size because they are connected to low voltage. Surge protector
1. Frequency conversion control cabinet must be added
2. Control cabinet using vacuum circuit breaker must be added
3. Incoming switch of power supply system must be added
4. Other control cabinets can be added. Of course, if there is budget space for safety reasons, they can be added. Surge protectors are generally divided into two categories: motor protection type and power station protection type. You must pay attention when choosing.
