In addition, generators over 15 kW must have the reactances (transient, synchronous, and subtransient, along with zero sequence), the power rating category, and the insulation class marked as well. Inverter-based generators need the maximum short-circuit current provided, in place of all the reactances except the zero sequence number. The nameplate must also stipulate how the generator is protected against overload, whether by…
