Power transformer differential protection is the main protection for powers transformers, using the principle of circulating current. Differential protection can quickly and selectively activate short-circuit protection in the event of phase to phase short circuit faults in transformer windings, outgoing lines, and single-phase turns.   The basic requirements for transformer differential protection are as follows:

The differential protection of power transformers is the main protection for a  transformer, which is installed according to the principle of circulating current. It is mainly used to protect various phase to phase short circuit faults that occur inside the windings of dual or triple winding transformers and their outgoing lines, and can also be

As a professional power transformer manufacturer in China, in last 30 years, our power transformer already widely used in solar power plants, in wind power plants, in hydropower plants, in some electrical substation and some coal power generation plants throughout the world. and the voltage level up to 500 kV. In this post, we will
