The components of direct currents equivalent to 1% and even 0.5% of the rated alternate currents must be tested, which is a relatively difficult technology in solar power generation and we are therefore looking for help or some technology in this area. The Problem Under the influence of temperature drift, sensor precision, etc., the output current of solar power exchange devices may contain weak direct currents, which may lead to the magnetic bias of grid transformers, as well as the abnormal heating and even burnout of transformers. |
