In the work of power workers, it is often necessary to conduct resonance tests on high-voltage power cables to identify the resonance point of the cable. Therefore, a series resonance test device is needed. However, during use, many power workers often report that the resonance point cannot be measured, making it difficult to achieve the desired effect of the instrument. This article will briefly introduce several main reasons why the series resonance test device cannot measure the resonance point.
1、 The equipment wiring is incorrect. The series resonance test device mainly includes fHV Hipot Electric Co., Ltd. main components: the test host, excitation transformer, reactor, and voltage divider. The equipment needs to be connected to the tested cable with connecting wires. If the wiring is incorrect, not only can the resonance point of the cable not be measured, but it is also very easy to affect the service life of the series resonance test device and even burn out the equipment.
2、 The equipment usage method is incorrect. During the use of the series resonance test device, it is necessary to strictly follow the instructions. Users can choose between manual testing and automatic testing. Regardless of the type of test, the correct parameter settings need to be made before conducting the point test, and then the correct steps need to be taken step by step. If the test steps are not correct, it is also difficult to achieve testing accuracy.
3、 The equipment does not isolate radiation factors, and strong electromagnetic radiation interference is often encountered in the use environment of the series resonance test device. If these radiation interferences are not eliminated first, they will have a great impact on the accuracy of the equipment, making it difficult for the equipment to test results, and the user does not know which step went wrong, wasting valuable time.
Overall, when using a series resonance test device, if power workers do not pay attention to wiring issues, usage methods, external radiation issues, etc., it is difficult to measure the resonance point. Therefore, users need to pay attention to these issues!
