lightning protection in substation

    Lightning Surge Arresters and Insulators Used in Transformer Substation In the design of protective means, engineers and technicians need to consider all aspects and Organically combine lightning-termination devices and lightning arresters to complement each other. The lightning protection design of substations is a common topic, and I don't think it is out of date to talk about it anytime. The reason why it is not outdated is that although the lightning protection design has been done all the time, and various related specifications are also emphasized, but in the actual operation of the substation, due to insufficient design or irregular construction (this article ends, not in-depth discussion) various lightning damage accidents occur from time to time, seriously affecting the safe and stable operation of power equipment and power grids, and also sounded the alarm to our engineering designers. How should this be designed? Only under the condition of not increasing equipment investment can we protect power equipment to the greatest extent and ensure the safety of power grid operation. This is an urgent problem that needs to be solved in front of our engineering designers.

  • How many of our most joyful memories have been created in front of a screen?
  • Communicating at great haste hones our utterances down to instincts and impulses that until now have been held back or channeled more carefully.

      But most of us can speak faster than we can type or text, and no-one complained that conversation makes our brains work too fast.
  • Our cafes, post offices, parks, cinemas, town centers, main streets and commu­nity meeting halls have suffered as a result of this development.

      Really? How many people met strangers in such places?

  • The difference between typing an email and writing a letter or memo out by hand is akin to walking on concrete versus stroll­ing on grass.
  • A butcher can tell you which cuts of meat are the freshest; an online grocer may not. That same butcher, if he is good, might not just remember your preferences—which an online retailer can do frighteningly well—but ask you how your mother has been doing, whether you caught the latest football game. These interactions remind us that we are more than con­sumers; they remind us that we are part of the world in a way no amount of online shopping ever will.

      This is right on the money - a visit to a local farm shop is a wonderful experience.
  • If we spend our eve­ning online trading short messages over Facebook with friends thousands of miles away rather than going to our local pub or park with a friend, we are effectively withdrawing from the peo­ple we could turn to for solace, humor and friendship, not to mention the places we could go to do this. We trade the com­plicated reality of friendship for its vacuum-packed idea.

      It might be just the way this essay was abridged for the paper, but I cannot see whether the author wants us to spend all evening writing a longhand letter to a distant friend, or ignore them altogether to spend time with a local friend.

    While I disagree with a lot of this, I recommend this essay anyway, as food for thought.
