Distribution Transformer Nameplate
A distribution transformer is an important electrical device used to transfer electrical energy from one circuit to another through electromagnetic induction. Distribution transformers are often located in utility poles or underground vaults, and they play a crucial role in delivering electricity to homes and businesses.
The nameplate of a distribution transformer is a critical component that provides important information about the transformer's characteristics to engineers, technicians, and maintenance personnel. This information helps them to operate and maintain the transformer correctly, ensuring safe and reliable electrical service.
The nameplate typically contains the following information:
1. Manufacturer: The nameplate identifies the manufacturer of the transformer, which is important for warranty and repair purposes.
2. Serial Number: Each transformer has a unique serial number, which is useful when tracking the transformer's life cycle, repair history, and maintenance schedule.
3. KVA Rating: The nameplate indicates the transformer's KVA rating, which denotes its capacity to transfer electrical energy from one circuit to another.
4. Voltage Rating: The nameplate reveals the transformer's primary and secondary voltage ratings, which identify the range of voltage that the transformer can handle.
5. Phases: The nameplate specifies whether the transformer is single-phase or three-phase, which determines the type of electrical service that the transformer can provide.
6. Frequency: The nameplate reveals the transformer's frequency rating, which indicates the number of cycles per second that the transformer can handle.
7. Impedance: The nameplate discloses the transformer's impedance, which represents the resistance that the transformer opposes to an alternating current.
8. Overcurrent Protection: The nameplate specifies the overcurrent protection settings for the transformer, which help prevent damage to the transformer and the electrical system.
9. Temperature Rise: The nameplate indicates the maximum temperature rise that the transformer can withstand, which is important for preventing overheating and damage.
The nameplate of a distribution transformer is a vital source of information that helps maintain the transformer's performance and longevity. Understanding the information on the nameplate can assist engineers and technicians in making informed decisions about the transformer's operation, maintenance, and repair. Overall, the nameplate is an essential tool for ensuring safe and reliable electrical service.
