Answer / Yogendra Singh Tomar

To reduce the circuit complexity of a star-delta starter using one timer relay and three contacts (for main, star, and delta), consider the following modifications:

1. Use a single contactor that can switch between Star and Delta configurations. This eliminates the need for an individual contactor for each configuration.

2. Replace the timer relay with a solid-state relay or digital starter, which provide more control and flexibility. They are compact, have fast switching times, and consume less power compared to electromechanical relays.

3. Integrate the start and stop functions into a single contactor for better streamlining of the circuit.

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
