Knowledge sharing about series resonant reactors
The fundamental reason for the slightly lower power factor on the input side of the frequency converter is fundamentally different from the low power factor of the three-phase motor with variable frequency. Series resonance occurs because the three-phase motor is a rational and objective electric...Read more -

Introduction about AC Series Resonance Test System
The generator AC withstand voltage test requires the use of power frequency voltage. The national standard defines the frequency of power frequency voltage as 45Hz to 65Hz. However, in many test scenarios, the generator is required to undergo an AC test of 50Hz ± 2Hz. Moreover, the generator stat...Read more -
The role of series resonant reactors in resonant circuits
As the name suggests, an inductor is a component connected in series in a circuit (an inductor). In the industries of reactive power compensation and harmonic control, the series inductors are mainly those connected in series with capacitors. The series inductors and capacitors form a resonant ci...Read more -

The main characteristics of series resonance
The main characteristics of series resonance: 1.The operation is quite simple. It is divided into two types: automatic test and manual test. The former can automatically find the resonance point and automatically increase the voltage, while the latter is for manually finding the resonance point a...Read more -
Detailed Explanation of the Differences between Series Resonance Test Equipment and Variable Frequency Series Resonance Test Equipment
The principle of series resonance refers to the situation in a series circuit composed of resistors, inductors and capacitors. When the capacitive reactance XC is equal to the inductive reactance XL, that is, XC = XL, the voltage U and current I in the circuit are in phase. At this point, the cir...Read more -
