The converter transformer is used to change AC  in one side into DC, mostly applied in an electrical swtichyard or an electrical substation. During its actual operation, the load current contains a large number of high-order harmonic components, resulting in uneven distribution of its internal losses and local overheating in a certain area. Excessive temperature […]

With the increasing strength and growth of the power grid network, the requirements for relay protection equipment in the power grid are also increasing, especially the requirement for speed has reached a high level. However, currently, the vast majority of electrical substations do not have busbar differential protection on the low-voltage side. In the event

For a completed solar project or a solar farm,  following testing items need to be carried out, which contain three main parts , Electrical testing for pre-fabricated box-type transformers or an oil-immersed distribution transformer, high and low voltage switchgear, and LV & Medium cables. 01 . Testing items for a pad mounted distribution transformer 1.
