1) why a dg set shows variation of power factor and load when synchronised with other dgs? 2)Why the load sharing is not become equal in all dgs?. 3)When a dg set will not run on auto start?
Is this possible to synchronize the two different ratings of dg
what is a diffrence between MCCB, RCCB, MCB, & ELCB ? what is rated current e.g. on motor name plate indicated that is rated curent? what is full load current? If we run D.C. motor with mechanical coupling and we measure voltage on terminal it shows voltage or not ? same in AC also possible ?
Why silica gel use?
How much current does a motor take in no load condition?
