The root cause of a cable failure is typically the breakdown of insulation, which can be triggered by various factors. As a result, cable faults are generally categorized into three main types: grounding, short-circuiting, and open circuits.
Locating the exact point of a power cable fault has long been a challenging issue for the power supply industry. Since these cables are often buried deep underground and their paths may not always be clearly marked, identifying the fault location can be extremely difficult. In many cases, it may take several days or even over a week to locate the problem, leading to unexpected power outages and significant economic losses. With the help of the HC210 cable fault detector, however, you can quickly identify and accurately pinpoint the fault, enabling prompt repairs and a rapid return to normal power supply.
Key Features:
The HC210 cable fault tester uses advanced fuzzy recognition technology to automatically analyze the test waveform, position the cursor, and display relevant fault data. It can also identify the type of fault and match it with the corresponding waveform pattern. The device offers seven working areas where users can simultaneously compare and analyze up to seven sampled waveforms, making it highly efficient for analyzing different cable testing methods.
Powered by an internal lithium battery, the HC210 can operate in environments without access to electricity, offering continuous use for more than 16 hours. It features a communication port that allows data to be transferred to a computer for storage or further processing. It can also connect to a micro printer to print out the sampled waveforms.
The HC210 is the lightest cable fault detector in the world, weighing only 0.75 kg with a compact and portable design. Its lightweight and small size make it ideal for field operations.
