W hen the electric auxiliaries are powered dire ctly fro the net and gen set, this
sw itching strategy indispensable because safe pow supply the auxiliaries is
not available. The itching
sequence follow s:
- net anom aly detected
- gen set started
- delay til gen set supply available after the norm circu it
breaker opened
- gen set irc breaker closed.
This can used hen safe xiliary pow supply available pow the
c irc breaker otor operators.
W ith strategy the itch ing sequence follow s:
- net anom aly detected
- norm line irc breaker opened and the gen set started
- delay til gen set supply available after the gen set circu it
breaker closed.The voltage ratings refer to:
- phase-to-neutral voltage the case single-phase operation
- phase-to-phase voltage case three-phase operation.
