Description
Overview
Portable Underground Cable Fault Locator, 380 V to 220 kV GAOTek is used to find underground cable fault. This system is designed for super wide voltage range from 380 V to 220 kV. This system covers all kind of cable faults like low-resistance fault (short-circuit fault, less than 100 ohm), broken fault (open-circuit fault), high-resistance leakage fault (more than 100 ohm) and high-resistance flashover fault (arcing fault).
Features
- Adopts dual-vernier auto searching fault, automatic displaying fault distance
- 4 in colorful touch screen
- Power-off wave saving, 64 units
- Built-in micro thermal printer
- COM or USB interface for uploading wave to computer
- Chargeable battery power, suitable for site use
- Compact size, light weight, water-proof housing
