what is called star connection and delta connection also
purpose of this connections?

Answer Posted / amol moon

In star conection Line voltage= Root3.Phase voltage, and
Line current=phase current, and Nutral is usedfull to
stable to voltage.
In Delta conection Line voltage=Phase voltage, and Line
current= Root3.phase current.when single phasing in delta
he worked v connection and incresed heatting.

In Air circuit breaker LSIG protection unit is used. Without fault in cables (2 runs 3Cx150Sq.mm Copper, 1Kv grade, XPLE armored cable IR value is more than 550Mohm @ 500V Megger) and load section Long time Overcurrent protection is triggers and trips the unit. We changed LSIG protection with new factory tested unit. Even then fault is persisting. Please suggest the possible causes
