Introduzione

UN30 trasformatore kVA is a versatile and widely used electrical device designed to step up or step down voltage levels for various industrial, commerciale, and residential applications. With itsmoderate power capacity, it serves as an efficient solution for small to medium-scale power distribution. This guide explores itstechnical specifications, common uses, selection criteria, and advantages to help businesses and engineers make informed decisions.

What is a 30 kVA Transformer?

UN30 kVA (kilovolt-ampere) trasformatore is amedium-capacity transformer that can handle30,000 volt-ampere of electrical load. Depending on its design, it can function as a:

• Step-up transformer (increases voltage for transmission)

• Step-down transformer (reduces voltage for end-use)

• Trasformatore di isolamento (provides electrical separation for safety)

Key Specifications

• Primary & Secondary Voltage: Common configurations include480V to 120/240V, 220V to 110V, or 11kV to 415V

• Single-phase or Three-phase: Suitable for different power systems

• Efficienza: Tipicamente95-98%, depending on design and load

• Cooling Method: Oil-cooled or dry-type (air-cooled)

• Classe di isolamento: Usually Class B, F, or H for thermal stability

Common Applications of 30 kVA Transformers
