Standard transformers (including non-isolated transformers) are designed to change voltage, which can be divided into step-down transformers and step-up transformers, with different numbers of turns in the primary and secondary coils. In some transformers, such as auto transformers, the primary and secondary sides are not isolated.

There are two ways to judge the fault of the transformer: intuitive judgment and analysis judgment. The fault analysis and judgment of transformers are mainly judged by the damage to the iron core as well as the short circuit between turns of the winding of the transformer.

Transformers with ferrite cores are non-conductive, ferromagnetic compounds with ferrite windings. Low coercivity and low eddy current losses make them ideal for high frequency applications.
Ferrite core transformers provide consistent performance under a variety of conditions, which is why they are so widely used in the electrical industry.

Dry-type transformers are being developed in an intelligent direction by State Grid Co., Ltd. and China Southern Power Grid Co., Ltd. in recent years Combining electronic, communication, computer and network technology with power equipment, monitoring, protecting, controlling, metering, and managing the power grid under normal and accident conditions, data transmission, remote monitoring, equipment predictive maintenance, etc.
