In this case, the primary of the transformer in phase A is shunted to ground, and lamp A receives no voltage. Similarly, if lamp B is dark and lamps A and C are bright a ground exists on phase B. If lamp C is dark and lamps A and B are bright, a ground exists on phase C. Figure 3-10.-An ac ground detector lamp circuit. 3-7

28So on a 3 phase ground fault detection system that uses 3 lights connected to each phase to show that it's properly working. I know that if one phase were to ground out the 3 bulbs that were on would now only have 2 lights on but they would be at a brighter capacity while the grounded phase bulb would be out. Let's say this system is 277V/480V.

PDF fileFigure 3 Solidly Grounded Four-Wire Multigrounded System Solid grounding reduces the risk of overvoltages during ground faults. These faults do not shift the system neutral (Figure 4b). Thus the system does not require as high a voltage insulation level as does an isolated neutral system. Transmission systems are typically solidly grounded throughout the world. Unigrounded distribution

093. Ground return. Ground-return relaying is illustrated in Figure 4. The ground-fault current returns through the CT in the neutral-bus to ground-bus connection. For feeder circuits, an insulating segment may be introduced in busway or conduit, as shown in Figure 4, and a bonding jumper connected across the insulator to carry the ground-fault
