In the realm of electrical engineering, a single-phase transformer is a fundamental component designed to transfer electrical energy between circuits using electromagnetic induction. This type of transformer typically consists of two coils of wire, known as the primary and secondary windings, wrapped around a shared iron core. Single-phase transformers play a crucial role in stepping up or stepping down voltage levels, making them essential in various applications, from residential power distribution to industrial machinery. Their versatility and efficiency in managing electrical power make single-phase transformers a cornerstone in electrical systems, ensuring the safe and reliable transmission of electricity. At ESU, we offer a range of single-phase transformers to cater to the diverse needs of electricians and homeowners in the San Diego area, providing solutions that align with the latest industry standards.
