The high current generator is a necessary high-precision, high-current measuring instrument in the laboratory. It is selected based on the measurement accuracy of the current transformer under different loads. Compared with ordinary ammeters, it has the advantages of simple structure, high reliabili
1 The vacuum degree of the vacuum bubble decreases1.1 Fault phenomenonThe vacuum circuit breaker interrupts the current and extinguishes the arc in the vacuum bubble, but the vacuum circuit breaker itself does not have a device to qualitatively and quantitatively monitor the characteristics of the v
The power quality analyzer is a high-precision testing instrument specially used to detect power quality problems such as waveform distortion, harmonic content, and three-phase imbalance that occur in the power grid. It has excellent functions and precise measurement capabilities, and can accurately
