1 Due to full compensation of resonant reactive power the power of power supply and equipment is less than 1/10 of the required capacity of the subject (1/q10); Small size and light weight with the same capacity large output capacity of the device and small power capacity required for configuration cheap convenient and safe operation. 2 Series resonance is actually a current filtering circuit so that the current passing through the subject is basically the fundamental current and the waveform distortion rate (THD) of the output voltage is very small which is superior to all existing ac voltage withstand equipment. 3 The short circuit current of the sample after flashover or breakdown is only less than 1/10 (1/Q) of the test current before short circuit which can effectively prevent the expansion of damage to the fault point after breakdown. 4ã??After flashover the arc will be automatically extinguished immediately. The long (number of seconds) process of restoring resonant state voltage after arc quenching is a steady-state establishment process and there is no danger of voltage overshoot and no danger of restoring overvoltage in microsecond millisecond transient process.

PM cores are a variation on classic P cores, suitable for large high power transformers and energy storage chokes. They have larger wire slots facilitating easy assembly, but still the good shielding of a closed core shape. PM cores can be found in transmission and radar equipment and in various high power industrial installations.
Transformer winding deformation test instrument based on the measurement of the characteristic parameters of transformer internal winding the internal fault frequency response analysis (FRA) method which is being developed in developed countries is adopted to make an accurate judgment of transformer internal fault. After the design and manufacture of transformer is completed the line coil and internal structure are determined. Therefore for a multi-winding transformer line coil if the voltage grade is the same and the winding method is the same the corresponding parameters (Ci Li) of each line coil should be determined. Therefore the frequency domain characteristic response of each line coil is determined accordingly and the frequency spectrum of the corresponding three-phase line coil is comparable to some extent. The distribution parameters of transformer windings will change when short-circuit between turns and phases occurs in the test process or collision occurs in the transportation process resulting in the relative displacement of the line coil and the deformation of the line coil caused by electromagnetic tension in the short-circuit and fault state during the operation process. Then it influences and changes the original frequency domain characteristics of the transformer that is amplitude change of frequency response and resonance frequency offset. The transformer winding test instrument developed according to the response analysis method is such a novel non-destructive testing equipment for transformer internal faults. It is suitable for the internal structure fault detection of 63kV ~ 500kV power transformer. product names Electric power transformer winding deformation test instrument Transformer winding deformation detector Transformer winding deformation meterTransformer winding deformation analyzer
