 Spanish term or phrase: Energía útil, de desfase y asimetría Energía útil, de desfase y asimetría These terms are taken from an article entitled "Modeling of three-phase three-wire electrical systems with unbalanced voltages ". If there are any electrical engineering experts out there I 'd be grateful for some help and a few website addresses. The sentence goes: "La modelización se realiza a partir del circuito real con la ventaja de poder separar los fenómenos energéticos de energía útil, de desfase y asimetría ". Any ideas how I could render this last bit?? Look forward to hearing your ideas. Desmond Electrical/Mechanical Engineering

 useful energy, of phase lag and asymmetry Explanation:Most systems are inefficient. Useful energy is the bit of energy that you can use, while all the rest is wasted. If you have the same sine wave on more than one wire, but they are not all at their peaks and troughs at the same time, that means that there is a phase difference, and you can say that one of them lags behind another. Asymmetry is self-explanatory, and just means a lack of symmetry. here is an electronics glossary http://ws3.tecnofin.com.mx/eshop/others/diccionario.htm#d Sorry, I can't find a power-electricity glossary.

6 hrs   confidence:
effective energy, phase shift and asymmetry

Explanation:
The last paragraph could be:
"Model rendering can take place from the actual circuit, with the advantage that effective energy, phase shift, and asymmetry phenomena can be separated.”

Note: phase shift, because it could be lag or lead.
