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.

The Isolation Transformers Functions is prevent electric shock accidents by isolating the two-phase electricity! We must first understand the power supply system in my country. The power supply system in my country uses a three-phase four-wire system and the neutral wire is grounded.

1.The dry-type transformer should be checked for temperature:
2.Check the oil level:
3.Listen to the sound:
4.On the top cover of a dry-type transformer, check the insulation:
5.Ensure that the bolted joints leading out of the busbar are not overheated:
6. … …

There are one or more coils on a winding. A transformer winding consists of bundles of copper coils, each with a different number of turns. It depends primarily on the input and output power supplies, otherwise it depends on the voltage range. The transformer winding diagram is as follows:
