南澳串联谐振装置的优点:

所需电源容量大大减小，串联谐振电源是利用谐振电抗器和被试品电容谐振产生高电压和大电流的，在整个系统中，电源只需要提供系统中有功消耗的部分，因此，试验所需的电源功率只有试验容量的1/Q.

2、设备的重量和体积大大减少。串联谐振电源中，不但省去了笨重的大功率调压装置和普通的大功率工频试验变压器，而且，谐振激磁电源只需式验容量的1/0，使得系统重量和体积大大减少，一般为普通试验装置的1/10.

改善输出电压的波形，谐振电源是谐振式滤波电路，能改善输出电压的波形畸变，获得很好的正弦波形，有效的防止了谐波峰值对试品的误击

4、防止大的短路电流烧伤故障点。在串联谐振状态，当试品的绝缘弱点被击穿时，电路立即脱谐，回路电流迅速下降为正常试验电流的1/Q。而并联谐振或者试验变压器方式做耐压试验时，击穿电流立即上升几十倍，两者相比，短路电流与击穿电流相差数百倍。所以，串联谐振能有效的找到绝缘弱点，又不存在大的短路电流烧伤故障点的忧患，

不会出现任何恢复过电压。试品发生击穿时，因失去谐振条件，高电压也立即消失，电弧即刻熄灭，且恢复电压的再建立过程很长，很容易在再次达到闪络电压前断开电源，这种电压的恢复过程是一种能量积累的间歇振荡过程，其过程长，而且，不会出现任何恢复过电压。

Advantages of Nanao Series Resonance Devices:

1. Significantly Reduced Power Supply Capacity
   The series resonance system generates high voltage and current through resonance between the reactor and the test object's capacitance. The power supply only needs to compensate for active losses in the system, reducing required input power to 1/Q of the test capacity.

2. Compact Size & Weight
   Eliminates bulky high-power voltage regulators and traditional HV test transformers. The resonant excitation power is only 1/Q of the test capacity, reducing system weight and volume to 1/10 of conventional setups.

3. Improved Output Waveform
   The resonant filtering circuit ensures pure sinusoidal waveforms, minimizing harmonic distortion peaks that could cause false insulation breakdowns.

4. Safe Fault Detection
   Under resonance conditions, insulation breakdown instantly detunes the circuit, limiting fault current to 1/Q of the test current. Compared to parallel resonance or transformer-based methods (where breakdown currents surge by 10-100x), this prevents thermal damage to fault points while precisely identifying insulation weaknesses.

5. No Recovery Overvoltage
   Post-breakdown, resonance termination extinguishes arcs instantly. The voltage recovery process follows a intermittent oscillation pattern, eliminating re-ignition risks and guaranteeing zero residual overvoltage.
