Yyy connection：What are the characteristics ?

The Yyy connection exhibits third harmonic voltage, but in three-phase three-legged core transformers, the third harmonic voltage does not exceed 5% of the fundamental. Therefore, it is suitable only for three-phase three-legged core medium to large transformers and cannot be used for three-phase five-legged transformers.

LuShan, est. 1975, is a Chinese professional manufacturer specializing in power transformers and reactors for 49 years. Leading products are single-phase transformer, three-phase transformers, DC inductors, AC reactors, filtering reactor, expoxy resin high-voltage transformer and intermediate, high-frequency products. Our transformers and reactors are widely used in 10 application areas: rapid transit, construction machinery, renewable energy, intelligent manufacturing, medical equipment, coal mine explosion prevention , excitation system, vacuum sintering, central air conditioning.
