KC India Test Laboratories LLP offers advanced and reliable High Voltage (HV) Testingservices to evaluate the dielectric strength and insulation integrity of electrical components, cables, and equipment. This test is a fundamental requirement in quality assurance, safety compliance, and performance verification in high-voltage systems.
High Voltage Testing is essential to confirm that an electrical system can safely handle operating voltages and occasional overvoltage conditions without breaking down or leaking current through its insulation.
What is High Voltage Testing?
High Voltage Testing—also known as Dielectric Strength Testing or Hipot Testing—is performed by applying a controlled overvoltage to an electrical product for a specific duration to verify insulation resistance and leakage current levels. The test helps determine whether the equipment can withstand operating conditions without failure.
There are two primary types of HV tests:
- AC High Voltage Test: Uses alternating current to evaluate insulation under real-world stress conditions.
- DC High Voltage Test: Uses direct current and is suitable for testing certain types of cables and equipment with lower leakage tolerance.
Objectives of High Voltage Testing
- Verify insulation quality and strength
- Detect manufacturing defects, voids, or cracks in insulation
- Ensure compliance with national and international safety standards
- Prevent future failures due to insulation breakdown
- Ensure equipment is safe for operation in high-voltage environments
