QLD-305TIME DOMAIN REFLECTOMETER TDR

New Products / New Technology

The QLD-305Time domain reflectometer TDR can be used to detect various faults in cables of different voltage levels, cross-sections, media, and materials, including measuring the distance of low resistance, high resistance, short circuit, open circuit, leakage faults, and flashover faults of cables. It can quickly detect the total length of cables and the distance of cable faults, while also calibrating the wave velocity of cables and determining the nature of cable faults. There are four testing methods available: low-voltage pulse method, pulse current method, multiple pulse method, and attenuation method.

QLD-D30 CABLE FAULT PINPOINT LOCATOR

New Products / New Technology

TheQLD-D30 Cable Fault Pinpoint Locator has four modes: acoustic magnetic mode, electromagnetic mode, step voltage mode, and audio mode, with seven methods. Its functions are even more powerful than the previous three instruments combined, making fault location simpler, more efficient, and more accurate. According to different testing environments, the corresponding fixed-point mode can be selected for testing; Cooperate with a DC high-voltage signal generator to synchronously collect signals generated at the moment of cable fault click through, using proprietary acoustic magnetic and electromagnetic signal synchronous display and intelligent algorithm processing technology to accurately locate various faults in power cables.

QLD-M61 CABLE FAULT TEST HIGH -VOLTAGE GENERATOR

New Products / New Technology

QLD-M61 Cable Fault Test High -voltage Generator is a pull rod high voltage device that integrates a DC high voltage generator, high voltage capacitor, high voltage discharge device, and safety discharge device. It can be used for fault testing of power cables of various voltage levels. It can generate high DC voltage, perform DC withstand voltage testing or burn through testing on faulty cables, and support digital positioning bridge testing for fault distance; It can also generate impact high voltage, causing the fault to click through and discharge, and use pulse rangefinders and fixed-point meters to test the fault distance and accurately locate it; It can emit electromagnetic signals and cooperate with electromagnetic detectors to achieve precise positioning of grounding faults and other integrated functions.
