RussianI want to add in my html page, so that it can use the highest mode available.
This is a good idea. In general IE should use it's best mode anyway, but occasionally (eg due to the user's browser config) it might default to a compatibility mode, which isn't great if your page isn't designed for it. So putting this tag into your page is a good way to mitigate against that.
Does meta http-equiv=“X-UA-Compatible” content=“IE=edge” impact on non-IE explorer?
No it doesn't. The tag is specific to IE, and is ignored by other browsers.
It was designed in a way that could have been used by other browsers, but it never was. I have seen a few older examples where people recommend specifying version numbers for other browsers, but doing so would never have have any effect.
The only option other than IE=whatever that is valid is chrome=1. But even this is only used by IE. It is used by the Chrome Frame plugin, to force a page to use the Chrome rendering engine within IE. But note that Chrome Frame is now deprecated, so you shouldn't be using this any more either.
So in summary: Yes, go ahead and add the meta tag to your code, and don't worry about it affecting other browsers.
