I. Overview
Fault location distance meter for power cables, designed for measuring the distance to fault points in power cables, featuring easy-to-identify waveforms, high resolution, user-friendly interface, and support for both touch buttons and mechanical buttons, easy to operate.
Can be used independently under low-voltage pulse mode; requires use with a high-voltage signal generator under pulse current mode; must be paired with a multiple-pulse cable test coupler under multiple-pulse mode; after distance measurement, a digital multi-functional cable fault locator must be used for pinpointing.ItWe jointly constitute a high-performance cable fault locating system that offers a variety of innovative features.
II. Features
1. Multiple ranging methods:
l Low-pressure pulse method: Suitable for distance measurement in low resistance, short circuit, and open circuit faults; also applicable to the entire length of cables and intermediate joints.TMeasurement of type connectors and terminal heads, as well as wave velocity calibration.
l Pulse current method: Suitable for distance measurement of high-resistance and flashover faults. Uses a current coupler to collect signals from the test grounding wire, completely isolated from the high-voltage section, ensuring safety and reliability.
l Multiple Pulse Method: The world's most advanced distance measurement technique, an improvement over the dual-pulse method. Waveforms are clear and easily identifiable, offering high precision in distance measurement.
2. 200MHzReal-time sampling:
l Domestic equivalent equipment*High sampling frequency, in line with international*Highly aligned with international standards.
l Provide*High0.4mThe distance measurement resolution is high, with a small measurement dead zone, particularly effective for near-end faults and short cables.
3. Touch operation and mechanical button operation
l Tactile buttons for greater flexibility, with gesture control functionality.
l You can drag the cursor, perform double-click operations, making positioning simpler and more convenient.
l Compatible with mechanical key operation, featuring a five-way key for more user-friendly operation.
4. LEDLarge-screen color LCD display, user-friendly interface:
l Waveforms are clear, especially during multiple pulse tests, where multiple waveforms are displayed simultaneously in different colors, making them easier to identify.
l 71. 1-inch large LCD screen160°Field of viewBrightness Achieved750cd/m2Meet the sunshine visibility requirements.
l The function menu is simple yet practical, with powerful features.
5. Picture-in-Picture Temporary Display Feature
l The interface display utilizes picture-in-picture mode, consisting of one main window and three temporary storage windows. This allows for simultaneous viewing of three temporary waveforms, simplifying, making it more intuitive, and convenient for waveform comparison functions.
6. Wavy Storage, Computer Online Communication:
l Large amounts of waveforms can be stored internally.
l UtilizeUExport waveforms data from the plate.
l Can be connected to computers (desktops or laptops) for online communication.
l Provide computer backend management software, forUData from rotating storage or online data is managed for data administration.
7. Power Management:
l Equipment is2No operation within a minute will dim the backlight.10No operation for a period of time will automatically shut down the device to reduce power consumption; when the battery voltage is low, the instrument will also automatically shut down to protect the battery.
l Built-in lithium-ion battery with a lithium battery charger, offering a reliable charging method.
l Long working hours: The instrument can operate continuously with a fully charged lithium-ion battery.7Hours above(Battery usage time will shorten after aging.)。
8. Rugged casing, lightweight and portable.
