Where Can I Find A Composite Surge Protector?
Where can I find a composite surge protector? Few people in the industry know about composite surge protectors, because there are few manufacturers that can produce them in the market today.
Where can I find a composite surge protection device? Composite surge protectors are very popular in the lightning protection industry. They combine the advantages of switch-type and voltage-limiting surge protectors. Among them, the advantages of no follow-on current and no leakage current are favored by more and more users.
1. What is zero leakage current
1. Composite surge protective device use a series combination of varistor and gas discharge tube or gap type (ram horn gap, graphite gap) as components. The gap acts as a switch, effectively blocking the leakage current of the varistor, so its leakage current is 0.
What is the meaning of zero leakage current of composite surge protectors? As we all know, the leakage current is directly related to the stability of the varistor, and at the same time to the service life of the surge protector, which is the most important indicator of SPD. Like a general single varistor surge protector, the service life is determined by the varistor, which is about four years. But the composite surge protector is different. Its service life will be longer than that of an ordinary modular surge protector, generally about 10 years.
2. What is the follow-up current of 0
Because the varistor acts as a circuit breaker, it can only pass a small current in the non-conducting state, which is not enough to become a follow-up current, so the composite surge protector has a follow-up current of 0.
The significance of the composite surge protector having a follow-up current of 0: the follow-up current is equivalent to the current exposed to the air, so its existence is a great safety hazard. Especially in wind power lightning protection, the follow-up current is exposed to the air, which will cause the surge protector to catch fire and cause great economic losses.
