As we know,charged clouds(from which lightning stroke initiates)may be charged with either +ve charge or -ve charge. Now say one cluster of cloude is fully charged with +ve charge & another cluster is fully charged with -ve charge. In the sky these two cluster of charged clouds have come in such a distance that, if they come clouser by some few yeards then the lightning discharge will take place between these two cluster of clouds. Under such a situation an Aircraft came inbetween. what happend??

2 11728I have tow 200 KVA UPS, both are in parallel mode.My question is that, both are running on battery when power fail, if one of them fail (Eg rectifire fails or some other reason), at thet time reverse power will come to faild ups if it comes then it will harm to failed ups or not? if not then how it protects to faied ups????????????????

1834what is the difference between the 94 lockout relay and 86 lock out relay. I have noticed that the 94 lockout relay is activated when the distance realy is activated and 86 is activated when the 87T differential is activated. but why can't the same lockouts be used for both the protection schemes
