UHV(L) Inductance Adjustable Power Frequency AC Resonance Test System

 

 

 

1. Due to the full compensation of reactive power resonance, the power supply and equipment are only less than 1/10 of the required capacity of the tested product (1/Q10); The same capacity is small in size, light in weight, the output capacity of the device is large and the power capacity required for configuration is small, the price is low, and the operation is convenient and safe.

2. Series resonance is actually a current filter loop, so that the current passing through the test product is basically the fundamental current, and the waveform distortion rate (THD) of the output voltage is extremely small, which is better than all types of existing AC withstand voltage equipment.

3. The short-circuit current after flashover or breakdown of the sample is only less than 1/10 of the test current before the short circuit (1/Q), which can effectively prevent the expansion of damage to the fault point after breakdown.

4. Immediately after flashover, the arc is automatically extinguished, and the process of restoring the resonant state voltage establishment after arc extinguishing is long (seconds) is a steady-state establishment process, and there is no concern about voltage overshoot, nor the danger of recovery overvoltage in the microsecond-level millisecond-level transient process.

 

 

 

 

 

Q: What is resonance of a system?

A: A phenomenon in which an external force or a vibrating system forces another system around it to vibrate with greater amplitude at a specified frequency of operation.

 

Q: What is the effect of resonance in a system?

A: The most important effects of resonance can be listed as follows: The voltages for capacitive and inductive system components increase. As a result, inductive and capacitive system components draw overcurrent. The isolation of the circuit components becomes challenging.
