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

arxiv.orgTransformer (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.
