The connection between transformer tester and power efficiency

The ratio of the output signal power of a transformer tester to the input processing power during additional task power is called the power of a transformer parameter tester. The transformer tester may not cause any loss, but in practice, this type of transformer tester is not available. The magnet......

How reduce the copper and iron losses of transformer?

1. Choosing a lower current density and reducing the number of turns will increase the magnetic flux density of the iron core and increase iron loss.

Common technical issues during transformer tester testing

In fact, the accuracy of transformer testers is not an important indicator of the instrument. In the transformer calibration regulations, it is required that the testing error caused by the entire circuit should not exceed 20% of the level of the tested transformer, and the presented data must be t......

Maintenance power of transformer tester

The magnetic flux of the transformer tester's iron core is related to the applied voltage. Transformer testers should be kept away from strong electric fields, magnetic fields, and high-frequency equipment. The smaller the interference of the power supply, the better. It is advisable to choose ligh......

Development status and trends of integrated substation automation

The substation is an indispensable and important link in the power system. It is responsible for the heavy tasks of power conversion and power redistribution, and plays a decisive role in the economic operation of the power grid. In order to improve the stable operation level of substations, reduce ......

Multiple methods for troubleshooting power equipment faults

In daily use, power equipment is sometimes prone to malfunctions, so analyzing the phenomenon and promptly identifying the cause of the malfunction is the key to identifying power faults. The basic theory of electricians is the foundation of analysis, which combines a full understanding of the struc......
