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 magnetic flux of the transformer tester's iron core is related to the applied voltage.

The transformer DC resistance tester should be kept away from strong electric fields, strong magnetic fields, and high-frequency equipment. The smaller the interference of the power supply, the better. It is advisable to choose lighting lines. Assuming that the power interference is still significant, the instrument can be powered by a communication purification power supply with a capacity greater than 200VA.

When working on the transformer resistance tester, assuming that the LCD screen appears disorderly and there is no response when pressing all buttons, perhaps the measured value is far from the actual value. Please press the reset button, or turn off the power, and then operate from scratch. The dry-type transformer tester generally does not add excitation current to the current due to the addition of network load.

Please press the reset button, or turn off the power, and then operate from scratch. Although adding the iron core to the load capacity will not saturate, it will increase the resistance loss cost of the coil, exceeding the additional capacity and the heat generated by these coil operations. Assuming that it cannot be dissipated in a timely manner, the coil will be damaged.

Assuming that the coil used is composed of superconducting research materials, increasing the current will not affect the heating of the enterprise, but there is also impedance caused by leakage magnetic in the internal management of the withstand voltage tester. However, as the current gradually increases, the output control voltage will decrease, and the higher the current density, the lower the output signal voltage. Therefore, the output power of the transformer tester may not be infinite.

Transformer tester is a power level tester closely related to transformer power. Generally, with higher power, the output power loss is smaller and the power is higher. On the contrary, the smaller the power of the dry-type transformer, the lower the power tester.
