1、 Principle of efficient three-phase synchronous measurementThree phase synchronous power on and independent samplingBy designing a dual power supply structure, a current (such as 20A) is applied to the three-phase winding of the YN connected transformer, and real-time data is collected using an i
1、 Core host componentsIntelligent cable fault testerFunction: Fault pre positioning is performed through low-voltage pulse method (measuring low resistance faults) and high-voltage flashover method (measuring high resistance faults), measuring the approximate distance of the fault point, the total
1、 Distance measurement principle (rough measurement of fault distance)Pulse reflection methodPrinciple: Inject low or high voltage pulse signals into the cable, and when the pulse encounters a fault point (impedance jump point, such as short circuit, open circuit, or high resistance fault), a refl
