Description

technical field [0001] The invention belongs to the technical field of cable testing, and specifically relates to a multifunctional cable testing system and a using method thereof. Background technique [0002] In power equipment, the smoothness of wired communication and the transmission of power depend on the normal operation of cable lines. Once the line is blocked, it will cause interruption of communication and power. If the fault cannot be detected in time and eliminated quickly, it will cause great economic losses and adverse social impact. Therefore, the cable fault tester is an important tool for maintaining all kinds of cables. The cable fault tester is a set of comprehensive cable fault detection equipment, which is used for testing the open circuit, short circuit, grounding, low resistance, high resistance flashover and high resistance leakage faults of power cables as well as coaxial communication cables and local telephone cables. Accurate testing of open cir...

Problems solved by technology

[0003] The capacitance capacity of the traditional high-voltage shock generator is fixed, and the output shock energy is sufficient when testing cables with high voltage levels, but when testing low-voltage cables, the output voltage of the high-voltage shock generator cannot be too high, so using high-voltage shock generators The impact energy output by the generator is too small, and the cable fault point is not easy to break down, which makes it d
