The purpose of this document is to highlight the special treatment or requirements of protection functions when applied to load commutated inverter (LCI) static starter turbogenerators. Static starting of TG's is accomplished by using an LCI, adjustable speed drive system, to motor the synchronous machine and coupled turbine. More specifically, the focus will be on 64B function (busbar earthfault protection) when achieved through 59BN function (neutral overvoltage).
