Applied Voltage Test Transformers With PD Free
It is primarily used to evaluate the internal and external insulation aging, contamination, dry and wet withstand voltage, and partial discharge levels of various electrical products, power products, insulated products, and insulated components. It is widely used in the electrical manufacturing sector, power operation departments, research institutions, and universities.
Functions
The 50–2,400 kV power-frequency test transformers with zero partial discharge are all first-of-their-kind innovations in China, offering the best and most stable performance. They have passed scientific appraisal and been awarded the title of “National New Product”; the contamination-resistant transformer has received a national utility model patent certificate; and the support transformer was the first of its kind to be manufactured in China. These products are primarily used by power transformer manufacturers (such as Shanghai Alstom and Guangzhou Siemens), with key technical performance metrics leading the domestic market and reaching the advanced level of comparable international products.
Characteristics
