impedance on transformer banks, or large single phase loads on the three phase network. Customer installation produced voltage imbalances are most commonly the result of single phase loads not connected evenly across the 3 phase system. Single phase motors, heating and cooling loads are very commonly connected in such a manner

Transformer (Vaswani et al., 2017; Devlin et al., 2019; Brown et al., 2020) has achieved great success in natural language processing (NLP). Benefitting from its self-attention module, transformer is born with the ability to build long-distance dependency, and which is also important to many visual tasks.
