Earthed system
WebHigh voltage systems (3.3 kV and above) on board ship are normally earthed. Such systems are usually earthed via a resistor connecting the generator neutrals to earth. The ohmic value of each earthing resistor is usually chosen so as to limit the maximum earth fault current to not more than the generator full load current. WebThe remainder of the installation is isolated by a 315 kVA 400/400V transformer: the isolated network is a TT- earthed 3-phase 4-wire system. Following the one-line diagram of the system shown in figure H1-8 below, a reproduction of the results of a computer study for the circuit C1 and its circuit breaker Q1, and C2 with associated circuit ...
