VLF TEST SYSTEM
Overview
The Very Low Frequency (VLF) Test System is an advanced system designed for underground power cable diagnostics. By applying low-frequency AC voltage, it efficiently identifies weak points, manufacturing defects, and installation errors before they lead to major failures.
TECHNİCAL FEATURES
• Output Voltage: 0-60 kVrms (AC) | 0 - ±60 kV (DC)
• Programmable Frequency Options: 0.01 Hz , 0.05 Hz , 0.1 Hz
• Test Capacity: Up to 20 μF
• Precision: ± 1% accuracy with 0.1 kV resolution
• Current Output: 0-60 mA, with 10 μA resolution
• Full Data Logging & Reporting Capabilities
• Wireless Tablet Interface for Remote Monitoring & Control
APPLICATIONS
- • Detection of manufacturing defects in underground cables
• Pre-installation testing before energizing new lines
• Routine maintenance for power distribution networks
• Fault location in aged or damaged cables
HOW IT WORKS?
- The VLF Test System applies low-frequency AC voltage to underground cables, analyzing insulation resistance and identifying potential weak points. The system then logs and reports results through an integrated computer interface for efficient fault analysis. The tablet-based remote control enhances safety by allowing users to operate the device from a safe distance.
