High Voltage Test Set
The HVG High Voltage Test Set, often referred to as a Dielectric Hi-Pot Tester, is a tough, precise, and incredibly dependable tool designed to check the dielectric strength of insulation in electrical equipment. This device is crucial for testing power cables, capacitors, transformers, motors, and various other electrical components, helping to ensure their long-lasting reliability and adherence to global safety standards.
The AC/DC Hi-Pot test, also known as the Dielectric Breakdown Test, plays a vital role in diagnosing insulation issues before they lead to serious failures. With more than 80% of faults in electrical and electronic systems stemming from weak or worn-out insulation—often due to dirt, grease, moisture, humidity, and thermal stress—Hi-Pot testing is essential for quality assurance and preventive maintenance.
