IEEE Trans Power Syst. 2016;31(5):3447 –56. 68. Krata J, Saha TK. Real-time coordinated voltage support with battery energy storage in a distribution grid equipped with medium-scale PV generation.
A transformer is energized when an initial inrush of current propagates in either the inner or outer coils. With two-winding or bidirectional transformers, naming conventions mirror the order of energization. Which coil is energized first makes all the difference.
Importantly, in grid-connected scenarios without storage, a wye with a neutral should be avoided on the transformer’s utility side. Such a choice runs the risk of circulating currents in the neutral, which, in turn, means more energy loss and overheating risk.
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.
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.
