Thunder detector iCoherer Lightning Detectorj  (USP 6,586,920)
This thunder detector says "PopovThunder".
PopovThunder is a high-performance thunder detector invented in Japan with much thunder
by a very unique original idea and it has epoch-making performance.
PopovThunder is Lightning Detect device. And PopovThunder is Lightning prediction device. 
Though PopovThunder does prediction of the outbreak of the thunderbolt, PopovThunder 
does not rely on Lightning directly.
Important Notice

When you use this thunder detector, you must know harm of the thunder well.

If your nation demands constant knowledge and skill from you about preventing harm of the thunder, and you do not have the knowledge and a skill, you must never use this thunder detector. Your nation may demand a necessary license to use this thunder detector for you. In this case you must obey this demand.

We developed this thunder detector to protect an electric and machinery from thunder. You must never use only this thunder detector for the purpose of protecting a person and an important animal, a plant, an important object from thunder directly or indirectly.

PopovThunder is for lightning protection such as electric facilities, or control system. You must never use PopovThunder for the purpose of protecting the body of the person from thunder.

The method to prevent harm of the thunder is studied by many people. It is one of the methods that you use the thunder detector. You must certainly use other effective methods together with this thunder detector so that you prevent harm of the thunder more surely.

When you use this thunder detector, at first you must do appropriate examination to follow the safety level related to the law of your country and the law about materials to use for connection and it to use this thunder detector, the design of the system. If a law and the safety level of your country do not accept the use of this thunder detector, it is impossible to use this thunder detector in your country.  

This thunder detector includes a harmful material and rare materials such as the lead, gold, palladium, and silver out of necessity to keep the performance. When you cannot perform the appropriate disposal that obeyed the rule that the country establishes of you when you finish the use of this product, you cannot use this product.  

The thunder is a natural phenomenon. The human does not yet know all of thunder. We do not compensate you for all troubles to occur by this product.

When the Japan government forbids that we export this thunder detector to your country, we cannot offer this thunder detector to you.

Z The detection reliability for 1,000,000 times of lightning affecting the electric circuit exceeds 95%. (As a result of own company test) When you used PopovThunder for the electric circuit definitely, the high detection reliability of PopovThunder offers the defense success rate more than 95% to your facilities for 1,000,000 times of lightning. The accident to be caused by PopovThunder having misjudged does not happen in Japan for 1000 years. (The total number of used PopovThunder ~ The number of years without an accident „1000 years)
Z It is the thunder detector which it developed for automatic control. Therefore, you incorporate it in the automatic system which accepted your purpose and can use it.
Z We use superior coherer (patent) for the long-term stability that we developed as a thunder detecting element newly.
Z PopovThunder can detect a thunderbolt to be generated with about 1(km) by superior electrostatic sensitivity from the setting place of this detector of the coherer before the outbreak of the thunderbolt.
Z PopovThunder can detect thunder by sharp selectivity for the thunder of the coherer under the heavy electric appliance magnetic fields such as transmitting stations.
Z With this thunder detector, the power line or metal telephone wire which can be connected to the exclusive Detection coil unit in your system become an antenna for the thunder detection. Therefore, it is not necessary for you to install an antenna for exclusive use of a thing of the thunder detection use outside your system. (Setting of extra appropriate SPD iLightning arresterj is necessary for a detection electric wire.)
Z PopovThunder detects only thunder with the influence in an electric wire connected to the machinery which is going to avoid influence of the thunder automatically by this detector. 
When influence by the thunder does not produce it in the electric wire which can be connected to the machinery which is going to avoid influence of the thunder by this detector automatically even if thunder sounds on a head, as for this detector, this detector does not work. 
Therefore, this thunder detector does not give an unnecessary thunder warning for automatic control.
Z PopovThunder detects big surge equivalent to this as well as thunder well. Therefore, in the cases that used this detector for a power line, you can know the circuit accidents (a thing with the spark in particular) to be generated with a power line and your facilities.
Z It is easy the size of the thunder detection unit that is the biggest part incorporates it in the automatic control system which you have already had with a small thing of 170~210~70immj with this thunder detector, and to use it.

Thunder sensitivity

When real thunder hazardous zone of the moment comes close to about 10(km), PopovThunder detects lightning occurring in Hazardous zone and outputs a warning signal. When real thunder hazardous zone of the moment comes close to about 1(km), PopovThunder outputs a warning signal without lightning.

œ A summary of the basic usage

 

@
¦1 You have to tie all machinery and facilities to be connected to the earth to equal electric potential to show it in the figure.
¦2

@

The metal power line and metal telephone wire which lead to your facilities from the outside. Among metal wire more than two of them considered to be it together, one of them must be neutral line connected to the earth outside.
¦3 You must use fuse which cleared a safe standard of your country definitely. With a normal blowout type fuse. It is standard 10 (A), and must be less than 20 (A). (The ability of the fuse must not be beyond the ability of the current breaker in the previous circuit.) You must not use the circuit breaker in substitution for a fuse here. You must not omit this fuse even if there are circuit breaker and a fuse in the system of the metal electric wire.
¦4 You must use SPD which cleared a safe standard of your country definitely. In addition, in this detector, the use of SPD more than 2,000(V) is impossible with both voltage restrictions start voltage and limit voltage.
¦5 When you connect detection coil unit and thunder detection unit with a coaxial cable, it had better not exceed 1 (m) in precision and should not exceed 5 (m) (5C-2V).
