can you give main difference between ELCB And RCCB?

Answer Posted / bad n

There are 2 types of ELCB ; voltage operated and current
operated. Current operated ELCB is RCCB or sometimes people
call RCD. Voltage operated ELCB have earth wire connect to
ELCB. It is for the ELCB to measure the leakage voltage and
will trip if the leakage voltage reach to dangerous value.
While RCCB (Current operated ELCB) monitor the different in
current between Neutral and Live(or phases). The
differential current is called residual current. RCCB will
trip if residual current reach at certain value depends on
rated RCCB sensitivity.

how does the terminal voltage of transmission lines increase when a capacitor is connected???? This happens not only in transmission lines but also in all circuits. How??? When a capacitor is connected in a transmission line, capacitor also takes energy from the same supply. But how is it able to increase the terminal voltage??? Practically What sequence of events happen during increase in voltage???
