We asked our electrician to double check the wiring connections from the generator, AVR and the monitoring system (measures through CTs and VTs). He found that some of the wires on the generator connections (as seen in the pic) were duplicated.
Good question on the ground - I will need to double check. RE nameplate, the handwritten notes are based on how the wiring was labeled by the folks that cleaned/reconditioned the unit.
Thanks for everyone's comments. The generator is rated for 400 kW - not 60 kW. We have permission from the utility - not our first rodeo with them as we have implemented an SEL protection scheme with a variety of protections and sensing on the mains. Here is a pic of how the genny is connected.
We have software that syncs our unit to the grid. It must match freq, phase and voltage before it gives the command to close the switch. We do not run a neutral, it is truly a ground, and yes, we complied with connection to the local utility in regards to interconnection requirements...
We have a 3 phase 480 v 60 kW generator that parallels the electric utility at 60 hz. The purpose of the generator is to generate electricity instead of buying it from the utility. When the paralleling switch closes, we see the the amperage on each leg climb quickly (up to 200 amps prior to...
