Introduction to AC Resonance Test System
An AC resonance test system is a crucial piece of equipment used in the electrical power industry. It is designed to perform high - voltage testing on various electrical insulation systems, such as cables, transformers, and switchgear. The principle of AC resonance testing is based on the resonance phenomenon in an electrical circuit. By adjusting the inductance, capacitance, and frequency of the test circuit, a high - voltage output can be achieved with relatively low input power. This method is more effective and safer compared to traditional DC testing methods, as it can simulate the actual operating conditions of electrical equipment more accurately and detect potential insulation defects more reliably.
