Description
The device of protection against emissions (retension) of PULSAR of a series 450 of ASCO firm (USA) represents the high-quality system of withdrawal of emissions of current developed for protection of the sensitive electronic equipment against the pulse hindrances and electric noise caused by transition processes in an electric network due to use of assemblies of the high-speed varistors from oxide of metal (MOV) which are picked up for the parameters with high precision.

Design (all in one) and technical parameters of suppressors PULSAR, allow to block all classes of protection. It is reached, first of all, by high speed, less 0,5ns (surpasses any analogs more than by 40 times), big reloading ability (even the most low-power model is capable to sustain current of a pulse hindrance in 40 000 And), complex protection (control of phase, linear tension, and also potential between a neutral and a contour of grounding is provided).

The majority of protection devices have time of reaction of 25 nanoseconds that not always provides the sufficient level of protection that demands its special design and multigradualness of the protection allowing to slow down the speed of increase of a pulse hindrance. A fact of common knowledge that 90% of lightning discharges have current of 20-30 kA, and time of its increase to the maximum value from 1 ms. At resistance of grounding of 4 Ohms, hit of a lightning with category current in 25 kA, will cause increase of potential in a network equal 2500B during less than 25 nanoseconds (the electronic equipment has to maintain without damage splashes to 1500B). It is obvious that at "unsuccessful" hit of such category the electronic equipment will be guaranteed it is put out of action, and the reason for that, insufficient speed of means of protection.


In case of a lightning discharge which has potential concerning the earth PULSAR rejects emissions of current on the grounding electrode (earth connection). However, for the majority of emissions at the transition processes created by the switched loadings, PULSAR takes away emissions of current back in a source, passing the grounding electrode.


By efficiency of protection of the electronic equipment against pulse hindrances of Pulsar has not equal, allowing to eliminate almost instantly the hindrances arising in the power supply network, controlling both the linear and phase tension, and also potential between a neutral and the earth.
