Operation Instructions for Cable Fault Simulation System

Pre-operation Inspection & Connection

Place the control cabinet and fault setting unit properly, connect power supply, communication cables and the tested 10kV three-core power cable securely. Check all wiring terminals to ensure tight connection without looseness.

Power On & System Startup

Switch on the main power supply. Launch the control software on industrial PC or laptop; wait for the whole system initialization and hardware self-check to complete normally.

Parameter & Fault Configuration

Enter the software background interface, select target fault point, then set required working status freely: healthy cable state, high-resistance fault, low-resistance fault or flashover fault. Customize fault electrical parameters as needed. The system will respond within 200ms after confirmation.

Carry Out Test & Calibration

Connect your cable fault detector to the cable under test. Run detection tests repeatedly to verify the locating accuracy, sensitivity and overall performance of the testing instrument under various fault conditions.

Switch Fault Conditions As Required

During testing, you can switch different fault types, adjust grounding resistance and breakdown voltage parameters anytime to simulate diverse on-site cable fault scenarios for skill training or equipment verification.

Shutdown Procedure

After all tests finish, restore the cable to intact healthy state first. Exit the control software safely, cut off system power supply, then disconnect all connecting wires and tidy up all accessories for storage.
