Cable Hi Pot Testing Service
Price On RequestCable Hi-Pot Testing (High Potential Testing) is a critical procedure used to verify the insulation integrity of electrical cables, especially after installation, repair, or during scheduled maintenance. This test ensures that the cable can operate safely at its rated voltage without breakdown or leakage, helping to prevent unexpected failures and downtime.
Purpose of Hi-Pot Testing
Detect insulation defects, cracks, or moisture ingress
Verify workmanship quality post-installation
Ensure long-term operational safety and reliability
Comply with regulatory and utility standards
Types of Hi-Pot Testing
DC Hi-Pot Testing
Traditionally used but now less preferred for modern XLPE cables
Provides high voltage to check leakage or breakdown
Mainly for older cable types or short-term field use
AC Hi-Pot Testing
Safer and more accurate for modern cable systems
Better simulates real operating conditions
Can be performed using Very Low Frequency (VLF) for field applications
Scope of Service
Pre-test inspection and cable preparation
Selection of appropriate test voltage and duration based on standards (e.g., IEEE 400, IEC 60229)
