An isolation transformer transfers electrical energy through magnetic induction. Due to this physical separation of the primary and secondary windings, any fault in the primary circuit does not directly affect the secondary circuit.
The 2023 National Electrical Code defines an isolation transformer as follows: Isolation Transformer. A transformer of the multiple-winding type, with the primary and secondary windings physically separated, that inductively couples its ungrounded secondary winding to the grounded feeder system that energizes its primary winding. Why isolation?
There may be numerous reasons for including a transformer in a design set. Maybe you are simply stepping PV voltage down to service voltage in a behind-the-meter context. Maybe your utility, inverter manufacturer, or authority having jurisdiction needs a specific type of grounding winding pair.
Rather than rather taking measures to lower the load or signal's THD, w Transformers with higher K-factor numbers—e.g. 20, 30, 50—are especially useful for circuits with known non-linear loads like computer servers, critical care facilities, and some hospital facilities. In low-voltage cases, K13 may be adequate.
For more in-depth info from the pertinent standards on THD and K-factor, check out ANSI/IEEE C57.96 and C57.110, as well as UL 1562 (medium-voltage, dry type transformers) and UL 1561 (low-voltage, dry type), and ANSI/IEEE 519.
