Answer / s.jayan

There are two by-pass systems, One is Static By-pass and
another one is Manual By-Pass. Static By-Pass works
automatically and Manual By-Pass operates only manualy.

Answer / asif

yes we have just 2 bypass auto and mannual when we use the
word ups it means auto matically but when we use dc charger
we can oprate mannually

Answer / shiv

There are two systems bypass one is auto and next is
manually.Which work the auto systems operate the self main
ups and manually not operate the non self so that any
costumer supporting the help.

Answer / muchha mondal

We know that primary transmission is done to reduce current so that i^2*r loss could be minimised but according to ohm's law v is directly proportional to i,which indirectly means higher potential difference means larger current?so how the current is minimised in high power transmission line??
