The variable frequency series resonant withstand voltage test device can conduct AC withstand voltage tests on cables. The data provided during the test is very accurate and applicable to various types of cables. Therefore, many people are curious about how this test device works and its working principle. The following article will explain it to everyone.
The working principle of the variable frequency series resonance withstand voltage test device: The variable frequency series resonance withstand voltage test device uses the working principle of series parallel resonance. By adjusting the output frequency of the variable frequency controller, the inductance of the reactor can resonate with the capacitance of the test sample after obtaining the frequency. At the same time, with the use of the frequency controller and the provision of power supply, the test voltage will continue to increase initially, so that high voltage will be applied to the reactor and the test object, and then the output of the frequency controller can be changed, causing the circuit to change its series resonance state. When using it, everyone must pay attention that the resonant frequency of the circuit depends on the capacitance and inductance of the test sample, and when adjusting the output voltage of the variable frequency controller, the high voltage of the test sample can also reach the desired voltage value.
Introduction to the Variable Frequency Series Resonant Voltage Endurance Test Device
The variable frequency series resonant withstand voltage test device is widely used in industries such as power, metallurgy, and petroleum. Its function is to measure the resonant voltage of the test sample, and it can also be used as an overvoltage protection signal during measurement. With the signal, everyone can use it to ensure safety.
